I love everything about Bui's. Food, quality, and service! Yes, service. I tend to binge on Bui's depending on what part of the school year I'm in. If I'm busy and lazy, it's Bui's for brunch everyday. Nowhere else on campus (and dare I say...Philly?) will you be able to fill yourself up on such good food with so little money. A foot long sausage egg and cheese sub for $3.50 is absurd in the best way possible. When ordering, don't forget the Bui's sauce! I suspect it's just a mix of mayo and Sriracha, but it's delicious nonetheless. While Mr. or Mrs. Bui's isn't going to serve you a sub on a silver platter, being able to text your order gives Bui's an A+ for service. Text your order 10-15 minutes in advance and they'll definitely have it for you! read more

A lot of people have called this great hangover food but my best friend introduced it to me as "Netflix food." She calls it the kind of guilty pleasure food you want to hold close to your chest and happily nibble on as you watch your favorite TV show and bum around on a weekend day (while procrastinating on homework, of course). I tried the turkey bacon, egg, cheese sandwich and was pretty blown away by how satisfying and tasty it was. Make sure to eat it while it's still warm. I was also so pleased to be able to choose turkey bacon (instead of regular bacon) as an option.Can't find that in most places! Additionally, the spicy Bui sauce definitely takes the sandwich to the next level. I expected it to be a red sauce but it turned out to be white -- interesting! Basically a spicy mayo. Can't wait to enjoy one of these when I visit Penn again! read more

I never got why Bui's is so apparently awesome. I must've missed the memo... It's alright. I've gotten a couple of the specials, and their subs are typically made with a combination or ham, egg, cheese, and/or condiments, wrapped in foil and ready to eat. I get that it's cheap and convenient, but so are most of the food trunks along 38th or Spruce. Someone tell me what I missed, please!!! read more

"Salt peppa ketchup Bui sauce?" Always Bui sauce. Always always always. Every breakfast sandwich from Bui's is on point on point on point. Super SUPER filling, delicious, cheap, and with quick service to boot! The long rolls are always so delicious and wonderfully chewy like some kind of magic French baguette. Again, they're pretty fast, but even so, if you don't want to wait, you can definitely order ahead! :) Last I checked, unlike Lyn's, Bui's is open 7 days a week. Lazy weekend mornings are made all the better with a Bui's breakfast sandwich. read more

You can't get much fuller for 4 dollars like you can at Bui's. What to get- egg, cheese, and... Steak if you're tryna do it up and be full (6 bucks) bacon, sausage, or ham if youre happy with any meat (4 bucks) mix veggie special if youre health conscious (4 bucks) ...but then maybe you shouldn't be eating here in the first place. Also, get the Bui's sauce!!! Its definitely siracha plus some other ingredients that add to its somehow appealing glowing orange color. Insider tip: this is the only food cart around UPenn where you can text in your order. Imagine this- sunday morning you wake up with a terrible headache from last night. All you can muster up is... steak, egg, and cheese with buis sauce and salt/pepper. Take a shower, walk over 15 mins later, and your sandwich is done for you. How heavenly does that sound? read more

Food (8.5/10) = After reading several yelp reviews, I decided to order "the Hangover" (Fried eggs, sausage, bacon, ham, and cheese, on a hoagie). Added sriracha to it. This is awesome breakfast food. It's so simple, yet so phenomenal. Really filling, and at a great price ($5). If I lived or worked close to this place, I would make Bui's a weekly thing. Ambiance (?.?/10) = it's a food truck Service (9.0/10) = very friendly, great smile Overall = If you live or work around this food truck and haven't tried it yet,...what is wrong with you? Go get yourself a "hangover" read more

One of the best, if not THE best, food truck in West Philly. All of their sandwiches are really, really good - filling, tasty, and cheap. I'm a huge fan of the Mr. Bui and the Mrs. Bui, and get them with Bui's sauce - some sort of sriracha mayo thing, but it makes everything better. Everything else on their menu is great too, and you can get the staples like a BLT/egg sandwich/cheesesteak too. They also have Orangina sometimes as a beverage item, and who doesn't like that? Mr & Mrs Bui are really friendly too, and once you've been there a few times, they start to remember your order. You can also call or text in your order for pick up which is really convenient if you're in a rush and want something quick to eat. read more

FIY: Bui's sauce is a must Breakfast sandwich trucks are a staple around Philly, especially in the University City area where poor college students are always hungry for cheap and fast food. WHAT I GOT: Ham, egg, and cheese with pepper, ketchup, and Bui's sauce PROS: Extremely filling!! These sandwiches are a bit longer than your average breakfast sandwich, though to me, the taste is pretty much the same. The Bui's sauce, which is literally just spicy mayo, adds a nice kick and flavor. CONS: I wanna say about 1/3 of this sandwich is bread. Bui's uses different rolls from other food trucks I've been to (Lyn's, Happy Sunshine, and Pete's Little Lunch Box) in that the rolls are THICK. Like we're talking at least an inch in width if you measure it after they cut it in half. I'm pretty sure the full feeling you get isn't necessarily from the fillings, but it's mostly from the ridiculous thickness of those rolls. It's also makes it hard to actually taste anything but the bread and sauces and maybe the egg. Their prices are also a bit higher than other lunch trucks I've been too. Probably because of the size of their sandwiches but seriously though, if I'm going to shell out a couple extra dollars for this sandwich, I kind of want to taste something other than bread, ketchup, and egg. Like where the frick did my ham even go? read more

Penn's famous sandwich cart. I'm always a fan of supporting my fellow Viets, and when I found out there were making sandwiches of all things(and not Banh Mi), I didn't know what to expect. Ordered from the specials menu because that's where it's at, and got the Hangover Special w/Bui's Sauce and the Mr. Bui w/steak. Hangover Special(3.5/5): I guess I really don't get these breakfast sandwiches for the most part. It is indeed a filling sandwich, and I was not unhappy with it. But given the ingredients(egg, cheese, bacon, ham, sausage), it's not terribly complicated to make and something I feel I could easily re-create at home if I bothered to. Mr. Bui(3/5): Seemed like a beef teriyaki sandwich essentially. Nothing to write home about. Didn't hate it, didn't love it. I'd probably stick more to the breakfast based sandwiches though because they pair better with Bui's Sauce(gotta love mayo and sriracha). As a sidenote, I find it funny that the most popular sandwich carts in Philly are owned by Vietnamese people, but don't sell the most popular Vietnamese sandwiches(Banh Mi, where you at?). While none of the flavors are particularly impressive, the combination of Bui's sauce and breakfast classics means that Bui's will never let you down for a consistently tasty and filling sandwich. read more

I'm sad to not give it a 5-star review because I really do love this place, but I'm annoyed that my steak, egg, and cheese is $5.75 (their other sandwiches are significantly cheaper), and that the ends of my sandwich are always empty bites of bread. Also, I switched over from the bacon, egg, and cheese to the steak egg and cheese because they're skimpy on the bacon and it's not great quality bacon. Then again, the steak isn't supreme quality, but it's a lot more filling than the bacon. I also wasn't a fan of everyone's favorite Mrs. Bui. A combination of the fact that the chicken was of way lower quality than I wanted it to be...it was like thin little pieces of chicken like paper thin..It made me slightly uncomfortable. And I also wasn't a fan of the spicy mayo tasting stuff that is Bui's sauce. I know, I know, blasphemy. Aside from that, I admit, I get a sandwich from this place probably about once a week, and it used to be much more often than that. They're pretty delicious. And so fast/conveniently-located on my walk to campus. Thanks Bui's, see ya soon! read more

Favorite breakfast sandwich truck in Philly. You can't go wrong with a sausage egg and cheese (I'm not a fan of bacon) or the veggie special. They can easily do egg whites and wheat rolls for the health conscious, and I always ask for extra ketchup instead of their mayo-based Bui's sauce. If you're in a rush, call in and place your order. No matter where you're coming from, it's generally ready by the time you get there. Or if you have a minute to enjoy the sunshine, you can chill in their lawn chairs and make some new friends. I would definitely call this place a University City staple. read more

Someone better call the cops because Bui's deals drugs. Don't believe me? Have any of their breakfast sandwiches and you will be a believer. They must lace every breakfast sandwich with crack because I get all itchy when I can't get one. On second thought, don't call the cops. I want this truck to stick around (: read more

Best egg whites and cheese in town! Speedy, friendly service. And for those of us that have to work while hungover on the weekends, this truck is a lifesaver. The only problem I have with them is that they don't make coffee. (This really only merits deduction of half a point but since that's not an option I have to round down). But really, it's not difficult to make and it would bring in SOOOOO much more money. This is a college campus where all the undergrads and grad students are zombies without coffee... Come on, Bui's, make coffee so I can give you that extra star. read more

order anything on the specials menu: notably hangover special, mrs bui, veggie special get all sandwiches with bui sauce. bui sauce is free. prices have gotten more expensive over the years. sandwiches went from $5-$6.50 and the sandwiches have been the same, maybe slightly less food read more

Definitely one of the best food trucks on Penn's campus. The breakfast sandwiches are an absolute staple and a must after a night out. The bread is crispy and toasted before being layered with eggs, bacon and cheese. The cheese steaks are also some of the best and the city and one of the best deals around at under $5. read more

Tried the hangover sandwich. It was good but nothing special about it... The food is more expensive than other trucks. I'm not really picky (an egg sandwich is just an egg sandwich), so I'm not really benefiting from the more expensive, "higher-quality" ingredients in this truck read more

So glad I tried this food truck out finally! I live right around the corner and decided to try this place today. Cheap and good sandwiches?? AND fast service? All possible thanks to Bui's. Sandwiches range from $4-$6. They have a menu, but really, you can just tell them what you'd like in a sandwich, and they would make it for you. I ordered the steak and eggs sandwich today with onions. My boyfriend got the pork roll, eggs, and cheese sandwich. The sandwiches are pretty big and filling. You can order with ketchup, salt, pepper, or Bui's sauce. Bui's sauce is a mixture of probably sirarcha and mayo. Tastes like spicy mayo really. Good stuff to top your sandwich with! The steak and eggs sandwich was great for what it is. Basic sandwich and simply delicious! Wish I added mushrooms to it! That would've made it a whole lot better. The pork roll and egg sandwich was probably my favorite from today though. We got Bui's sauce to go with it, and it complimented it pretty well. If you're in the area and want to grab something quick, cheap and good, definitely come to Bui's! read more

After years of patronage, I can't believe I haven't written a review for Bui's. This is the perfect food cart in my eyes: family run, cheap, interesting, and delicious. I'm ashamed to say we get the same damn thing every time, because we love both items: Mrs Bui and the Hangover Special with Bui Sauce. I swear, we drive twenty blocks each way just to get our fix on Saturday and Sunday mornings. When you're in the mood for a filling, awesome sandwich, look no further! read more

Having attended Penn, I can tell you that the reviews are right - their egg and cheese sandwiches are the best cures for a hangover. The breakfast sandwiches are a bit on the salty side, but nothing will make a Saturday morning (or afternoon) seem less miserable after a few too many drinks the night before. Even when there's a long line at the cart, the owners do a good job of moving the line and getting the food prepared quickly. I dock Bui's one star because their cheesesteaks are mediocre; I don't expect something at the level of Pat's, but there's not enough cheese to merit calling this a cheesesteak. If you're looking for an on-campus steak, walk up half a block to Steak Queen. Aside from that, though, the rest of the food here is solid if unspectacular. And did I mention that the food was cheap? Getting a footlong breakfast sandwich for $2-3 truly felt like a godsend some of those mornings. read more

I had passed by Bui's a million and one times, but never really thought much of it. I don' know why, but I just was not drawn to trying it. So, the other day, like I often do, I whipped out my I-phone, pulled up my Yelp app, and decided to see what was near by and rated well. I was surprised to see after 40 reviews Bui's Lunch Truck had 4 1/2 stars, with a healthy littering of 5 star reviews. So, I had to try it. A lot of reviews mentioned their breakfast sandwiches, but I am usually not the breakfast food for lunch type. So, I decided on the Mr. Bui special sandwich. In a nutshell, it's a cheese steak with peppers and teriyaki sauce. The bread was a little on the crisp side. It tasted okay, but I prefer it a little softer. And, to be honest, for the extra buck, the peppers and teriyaki sauce were not worth it. But getting past that, the steak and cheese were good. If I was to go back, I'd get a basic cheese steak. Not one of their variations of a cheese steak. Either that, or I go for breakfast and find out what all of the rave is about. read more

Bui's was my first ever Penn food truck experience (thanks to an extremely hungover friend who asked me to get him a Hangover Special from Bui's) and I must say, it blew away the standard I held for food truck breakfast sandwiches! I had ordered a simple ham, egg white, and cheese on a bagel with light ketchup and pepper. Though the sandwich is uncomplicated to make, it's the fact that it wasn't greasy and sloppy - that is what impressed me about Bui's. The egg wasn't wet and slipping out, the cheese wasn't gooey and running down the sides, the bagel wasn't hard to chew - just none of that! It was a simplistic and beautifully prepared sandwich, especially considering since there was a crowd of hungover students waiting to get their food as well. Bui's is definitely a good option to consider whether you're hungover or sober, taking a lunch break, or grabbing food to eat while binge watching Netflix,. Quick, cheap, and made with love, the people at Bui's definitely know how to make breakfast sandwiches. read more

Delicious, simple egg sandwiches with fresh bread. Fast service, cheap prices. What more could you ask for? Service isn't stellar and it sometimes is hard to hear and understand the people from the truck, but it doesn't faze me too much. read more

I always get a Mrs. Bui. Solid sandwich. This is the best place to go for breakfast or lunch. The sandwiches are fairly cheap, and the people are fast. There will most likely be a line, but it is definitely worth it. read more

I've always come here for the bacon, egg, and cheese sandwich with Bui's sauce (it's sriracha mayo). It's pretty cheap and is always delicious. And it's always made super fast. You can also text or phone in your order 5-10 minutes before you get to the truck so you can just walk up to the truck, pay, and not have to wait if there is a line. The woman who usually works in the truck is very hard-working, cooking, taking phone call and text orders, and keeping everything together. She's awesome! read more

BEST LUNCH TRUCK EVER. Delicious. So friendly. Learn your order after you come a few times. And the prices are incredible. One star off for being closed when you say you are open! Makes me so sad! Why do you close at 3 pm ?!??! SO SAD. read more

Turkey bacon, egg, and cheese. Bui sauce and ketchup. That's what I get every time. i call Rachel about five minutes ahead of time, and it's always ready for pick up when I get there. Best breakfast sandwich and that Bui sauce! Creamy with a kick! And the baget is always toasty with the right amount of crunch. read more

The gym of Philly. Best tasting breakfast at very reasonable prices. Nice portion too. You can't find better value anywhere else. Make sure you get "mr. Bui's sauce" on it. read more

Bui's - Mr. Bui - Sandwiches Near Me - Philadelphia, Pennsylvania

Bui's is legit, I always get the breakfast sandwiches which are really cheap and the eggs are fresh. I get them with srichicha or bui sauce and sometimes with coffee or a juice. It is really cheap and when the line isn't long for lunch, i get a chicken sandwich gyro or chicken parm which are all on point. Mr. and Mrs. Bui are really nice people and wonderful cooks read more

This food truck is half the reason I moved to Philly. Kidding kinda. But really the breakfast sandwiches with Bui sauce are amazinggg. Always get the sausage bacon egg cheese with extra bui sauce. Don't forget the extra bui sauce, really makes the sandwich. Also love that you can text in your order to pick up. Highly recommend this food truck! The best hangover cure read more

Bui's - Sandwiches Near Me - Philadelphia, Pennsylvania

See all

I've only been here once. Got a couple breakfast sandwiches that were pretty good. The bread was fresh, but they add a spicy mayo sauce that I didn't know about and that completely ruined my egg & cheese sandwich :( other than that it was pretty standard breakfast. read more

Very good and fast sandwiches. Just had sausage and egg on a large roll for only $3.75. Always gets you the sandwich quickly. Open 7 days during College school year. read more

Yes indeed, the only thing I've ever purchased from Bui's is the egg sandwich. Fresh roll + perfectly cooked eggs + made to order + *cheap* = bliss. I keep it simple: egg whites with cheese on a long roll. They don't look at me funny if I ask for just 1 piece of cheese or black pepper. read more

Bui's sandwiches are perfect for mornings on the go--simple fresh-made goodness that's super affordable for students (cash only). Sandwiches can be topped with "bui's sauce" (which is essentially a delicious spicy mayo), ketchup, and s&p, so be ready to specify your condiments. read more

Excellent breakfast sandwich (get the Hangover Special...DO IT!!) and a decent Philly cheesesteak. Prices are very reasonable and Mrs. Bui (if that's her name...) is so sweet! There is this one creepy dude though who speaks in a really high voice who works there (Mr. Bui?). I actually never really noticed until a friend pointed this out to me. But I digress...this is probably the best breakfast sandwich truck on Penn's campus, so go! read more

in two words: THE BEST in a few more words: this place is an egg-and-cheese mecca. nothing beats spending pocket change on one of these heavenly sandwiches. read more

Best breakfast cart in University City. If you're a Penn student, you know Bui's as THE magical hangover cure on campus. If you aren't hungover, it's still a filling, cheap, delicious way to start your day. I usually get the veggie special with Bui sauce (some heavenly combo of mayo and sriracha) and I highly recommend you try it too! read more

Oh Dr. Bui and your instant hangover cure...I never actually ordered anything other than what's on their breakfast menu, so I can't tell you how good their cheesesteaks are. It doesn't matter though, since nobody goes to Bui's for anything other than their glorious breakfast sandwiches. Forget Steak Queen- Bui's has perfected the art of the fried egg sandwich. Back in the day, I rarely deviated from my staple of ham and egg with saltpeppa, and that's the way I liked it. At $2.25 a sandwich (cheese was an extra twenty-five cents, I believe), Bui's was (and is) by far the best bang for your buck you can get in University City. I'm pretty sure they singlehandedly raised my cholesterol by twenty points between my junior and senior years at Penn. read more

These are legit breakfast sandwiches!! I always order the sausage, egg, and cheese sandwich, and it's always consistent, delicious, and filling. I would suggest trying the bui's sauce at least once, it compliments the sandwiches nicely. Also, this is really cheap and usually pretty fast. Overall one of the best food trucks on Penn's campus. read more

I love their Vegetarian sandwich (special #4). the bread is toasted to perfection and the combination of spinach and eggs is mouth-watering. Overall it is very tasty. read more

Good prices, lightning quick service, but the sandwich was only alright. Supposedly great for breakfast, not a great lunch place.
