A sandwich is a sandwich so I guess what makes this place good is the plethora of options and customizations. If you didn't like your sandwich, you just didn't order right. I prefer which which over most other sandwich chains (togos, quiznos, subway). read more

I ducked in here for a late lunch between errands. Originally I was going to go with the tried and true (Au Bon Pain) for the grab-and-get-out experience, but the line was slooow and the cash register line did not look promising as it was also stretching back and featured a mass of seething customers. I getting hungry, and with the time for my brow wax appointment looming, I decided to check out Which Wich. I must have timed it right, as there were only two people ahead of me in the line. The customization looked ambitious, so I decided to grab a bag for the #8- Banh Mi as this is not something I could find at the ordinary sandwich place. I decided to go with the standard option- cucumber, siracha mayo, jalapeno, cilantro, and pork. I was a bit wary of the pork, but figured in for a penny, in for a pound. The fountain drink selections are solid - they have Barq's root beer - so I grabbed my drink, secured a seat, and waited for my order to be called. All was well until I heard, "Banh Mi, no name" called from the counter. Apparently, I was meant to write my name on the bag. For some reason, that had escaped me, though to be fair there were a lot of decisions to be made when it came to crafting my sandwich - even though I went the lazy route. Perhaps it is time for an eye exam. That aside, I found the sandwich to be flavorful, with just the right kick of spice afforded by the jalapeno and siracha. The bread was crisp, without shredding the roof of my mouth, unlike some other banh mis I've sampled. When I looked at my receipt, I noticed that I can go online to take a survey and write down the code to redeem for a free cookie (w/purchase) on my next trip here. Recommended if you are in striking distance of Block 37 on a day when The Nosh is not on offer. read more

They have delicious breakfast sandwiches! The owner is so nice and the breakfast sandwiches are fresh and they are made to order.

soo many Choices! i cant wait to explore (devour) more of this amazingly complex menu. I'll admit that at first it is kind of intimidating how you have to pick a bag that corresponds to the category of sandwich you want. i was in the mood for pickles and pork, so i got the Cuban. the gf got a spicy mayo shrimp po'boy. the sandwiches look small in size, but they are heavily packed with dense consumable contents. idk, i'm kind of at a loss for words because the sandwich choices, options, and add on's are literally endless. the wheat bread was reminiscent of potbellies when toasted but the flavor of Which Which is off the Heezy. Fo-Sheezy living @ the forest park blue line stop i imagine riding the train down to Block 37 (newer awesome mall on state street) to get some Which Which up in this bitch. i'm sooo hoping they expand throughout chicago. read more

Fat happy Americans love too many choices so of course Which Wich is going to satisfy our ever-growing need for control and options!! YAY - sandwiches where you can decide spicy mayo or regular mayo (shoot, maybe even light mayo...). Dijon or yellow mustard? Veggies? Cheese? All of these decisions are made while scribbling down your selections on a brown paper bag. It's like every other sandwich joint BUT NOT. read more

I have gone to this place a few times for lunch and I enjoy it enough to go back. The options are almost limitless. You start with the bag of the type of sandwich you want then you pick which of those categories you would like. Then you build your own sandwich. The sandwiches are pretty good and filling. The service is a little slow even when it is not that busy. There are a lot of choices plus they have Mr. Pibb which I enjoy. I would recommend this place. Try one of the Italians! read more

The taste of the sandwich totally depends on what you put on it. You pick your bread, meat, toppings, dressing and condiments by filling out the menu/sandwich bag before ordering. Then 5 minutes later, you've got your sandwich. Fast and simple. The chicken + avocado + mayo + lettuce + ranch is a great combo. I'll be back to try more options. read more

Like potbelly but better. Dig the people and the concept. Get the wicked

Today I tried the small Italian sandwich. I must say I was underwhelmed. The meats and veggies were fresh, however the bread was very dry and hard. It reminded me of saltine crackers. I'm a bread lover so if the bread isn't right is hard for me to enjoy my sandwich. Not sure if I'll give them a second try or just go to potbelly's next time I have a taste for a good sandwich. read more

This place is very a interesting and unique version of subway. You walk in and choose a paper bag with a number (1 for turkey, 4 for chicken, etc). Then you take a marker and fill out the info on the bag- how big, what kind of bread, what kind of cheese, what vegetables you'd like, etc. Then you turn it into the cashier and pay (about $5.75 for a 7 inch.) I had a turkey on wheat, toasted, with mozzarella, lettuce, tomato, mushroom, olive, cucumber, oil, vinegar, and oregano. It was very tasty- bread was nice and soft, veggies were fresh. But even though I chose tons of veggies, they only barely put a few of each on the sub. I would have like more stuff on it. Seating area is small inside but decent. And as soon as we sat down, someone came and wiped down our table- a nice touch. I would come back here for a quick and yummy lunch! read more

I like the concept, and the ease of marking what you want on a bag and not trying to tell someone what you want; no more "not peppers, pickles" that I've experienced. Plus they have one of the best chicken salads I've ever tried. read more

Yummy tasty sandwiches and a fun "write on a bag" system. Vegetarian friendly, creative, and we wish we had one in Boston!

Wonderful sandwiches, lots of options, and great for vegetarians (fewer options for vegans) but kind of loud. Love any sandwich with their olive salad or spicy mayo. read more

Great food, very cool and unique way to chose the way your sandwich is made. Cool employees, great food, good prices.

Very good sandwiches, very good selection of toppings and meats. This isn't the place to go if you're indecisive, as you'll be choosing everything that goes on your sandwich / salad. But if you like that kind of thing, then you'll really like this place. A little pricier than I'd prefer, but considering the location, it's about average. read more

This place rocks. I wish there was a which wich north of the loop so I could go more often including weekends. Service with a smile, food with a flavor. Who DOESN'T like customizing their sandwich? Fool-proof. read more

I was pleasantly surprised by this place. I take a ho hum approach to sandwich shop, as they're just a place to get lunch and get back to work. But when I had to work at my Loop office on Saturday, I realized not much was open. I remembered Gallery 37 having some downstairs options and knew they'd be open since the "mall" caters to tourists. So I grabbed a sandwich here. I'm a vegetarian and I loved that it had several options for us. I also loved the unique options to add to sandwiches (hummus, house chips, dried cranberries, walnuts). Being a first timer, I ordered a "medium" thinking that would be a sufficient size. It was HUGE, far too big for one meal. But it was a fabulous lunch! read more

Was my mistake that I got the Tuna? Because I could have gone to subway for the same exact thing. I asked the kid if I could have it toasted, but I don't want the tuna hot. He just told me to put down cold. Well, that's how I got it. Not toasted. Is it just me or does everyone in Az. have soft teeth? Are your gums hurting? WHY CAN I NOT FIND A SANDWICH PLACE WITH GOOD CRISPY BREAD! It's all dough! First of all, stop storing it in plastic. It makes it soft. It has no taste. I'm really not being a snob. Promise. I love a sandwich, but its not just the fixings, the bread has to make its own statement. The bread I grew up on could be eaten as a meal on its own. This bread and every other I've tasted here can only be used to sop up spills of some kind. Is it the water? dunno. Ill keep searching. read more

My second time here back to back! Try the Wreck sandwhich , delicious and fulfilling and the choices of add ons to your sandwich are good. So try it, I like there set up as well in regards to each sandwich. read more

I don't know about this place - the food is no better than an average torpedo sub place and the service was really lacking. They seemed really interested in not being interested with me. The cookie was really odd flavored for a chocolate chip cookie. Not a big fan of Which WHich. read more

I went in with some friends today. First off, it wasn't so busy so we got to order pretty quickly. There are so many choices of sandwiches to choose from it is overwhelming but awesome for those picky eaters out there. Grab a bag according to the category of your sandwich (vegetarian, Italian, breakfast,etc.) and then choose what you want on it. I loved it. Tasty and good prices. I tried the Italian pizzawich.... it was really good! Definitely gonna hit this spot more often! read more

The sandwich was pretty good, and I love the concept, but on my first visit someone just walked of with one of my sandwiches. Luckily the manager believed me and made me another. read more

Literally the best sandwich i've ever had. I ordered the chicken pesto sandwich and man oh man it was freaking delicious! This place is all about customization and creativity, the options are endless. Only complaint I had was the wait time. It took about 15 mins to make my sandwich, can't imagine how long it would take on a very busy day. Overall, this place is awesome and I will definitely come back! read more

I love this place! I have been to several other locations in addition to this one and the sandwiches are always fresh and delicious. I generally order a chicken or chicken salad sandwich, and you can basically whatever toppings or sauces you want (they have a ton of choices). I will say that when I went here during lunch hours, it took at least 10-15 minutes after I ordered to get my food, which isn't that long, but not fast for a quick sandwich place. Other than that, I love the number of choices you have and different combinations of sandwiches you can make. read more

This place is pretty awesome, great sandwiches in the Washington blue line stop, great vegetarian options, huge sandwiches that you need to unhinge your jaw for. read more

Went back a second time as I thought I'd give them another chance. Ordered egg salad again. This time the girl toasted it without telling me. I told her I did not like warm egg salad. She replied they toast everything. I got the manager and he told her to re-do the sandwich. I was there at 12:30 p.m. and the only one in there. Gee, I wonder why. read more

I like Potbelly's but at Which Wich was reminded of how a Potbelly's chicken salad sandwich tasted 10 years ago. Also Grahamwich take notice - it is possible for customers to select what they want on a sandwich. Highly recommend to the quickie lunch crowd. read more

I doubt I'll go back, at least during the work week. Went in on a Friday at 12:45, filled out the bag to order a turkey sandwich, waited 20 minutes, then realized they made me a corned beef sandwich instead. They figured out the error, but I still had to wait another 5 min for the turkey sandwich, with no explanation. The guy that handed me the sandwich tried to cheer me up after he could see the anger on my face, so that was admirable. The sandwich itself was OK- not as good as Potbelly's though. There's just too many other good options for a quick lunch in the area for me to ever go back. read more

Love it. You can be as creative as you want in putting together your sandwich, meaning there are endless combinations. The food is the fresh, the service is good, and the wait isn't long. I would recommend that you don't come in too late in the day (which I've done a few times) as they will run out of random ingredients and ruin the composition of your perfect sandwich. The only thing I would caution about is that for first timers the system can be extremely confusing. Paper bags and sharpies and what not... I had some trouble finding the place the first time, but just be sure to head to the basement level and you will find the restaurant there. read more

Tried it, but was disappointed. I loved the variety of options offered, but the end product was like a low-grade PotBelly's. Note "Toasted" = slightly above room temperature. read more

I ordered online with uber eats and saw that is was "being prepared" for 15 minutes and then deliver took 13 minutes, so not bad really. The sand which is so big! And full of toppings. My only complaint was it was a little salty, other than that really pleased. read more

Which wich was a disaster as far as I am concerned! The do-it-yourself atmosphere has reached a new low here. One does everything except make the mediocre sandwiches. And it is expensive. I spent $12.35 on a modified Reuben, chips (packaged Doritos) and a fountaion drink -- modified meaning I ordered only corned beef, Swiss cheese and mustard. None of the goopy slaw or kraut for me! And it still took over 15 minutes to get my sandwich. They had one poor guy making all the sandwiches and screaming out names badly. To me, I waited a long time for little results. The sandwich was pretty dry and I got one shaved slice of Swiss cheese as a reminder I ordered it. Subway is faster, cheaper and you get better results. That's all. read more

First time coming here and the sandwich was yummy. I would not have stop if the employee wasnt giving samples. I ended up with the roast beef and it was pure heaven. The cookie wasn't that great. It reminded me of a generic homemade cookie. The milkshake was good to. I will come back. read more

They really need to do something about this place's layout. There's a stand out front with the bags you use to order, but there's also a wall of bags immediately as you walk in, which creates a situation like I found myself in this afternoon. I had filled out my order and thought I was in line, but it turned out I was standing behind a group of 3 or 4 people who couldn't decide what they wanted, were taking pictures of the menu on their phones, changing what they wanted on their little bags- basically after a few minutes it seemed pretty clear they weren't ready. So I made my way to the register since I had been ready for about five minutes, at which point the dad of the group started bitching at me that they were in line. I pointed out that they were still deciding, to which he whined "but we're in the line, dude". So I left, because the food's just not good enough to deal with drama. I will say the Cobb salad wrap is pretty good and the employees are always very nice. But the ordering system is a hot mess. read more

I went here for the first time today and won't be back. No one helped us for 10 minutes (no other customers and 3 employees). Finally someone came up, I assumed to great us, but he just said excuse me and grabbed himself a Gatorade. When we were finally help the man was extremely pushy and obnoxious. When I finally got my sandwich it was disgusting. I took two bites, threw it out, and went to jersey mikes, which was packed, but I got my food faster and as always, was great tasting. read more

Just opened in Block 37. I like the ordering system - you check boxes off on a cute paper bag - and they have a lot of interesting combos you don't see elsewhere. I guess my problem was getting a salad (yeah, yeah) - the whole thing was meh. First, I got teriyaki chicken, which came out resembling sliced turkey lunchmeat with no teriyaki flavor whatsoever. Second, the lettuce was simple iceberg, disappointing, and the veggies were sparse. Third, they forgot an ingredient, which happens, but when I went back they said it would take 5+ minutes to prepare said ingredient. They did offer me free chips, which was nice (didn't take them up on it). I might try again next time for their sandwiches, but the meat on my salad really did throw me off. Finally, the space is kind of spare and uncomfortable - the tables and chairs reminded me of a bus terminal or something. Not a pleasant place to eat in. read more

I really liked Which Wich! I thought it was super fun, quick and tasty. I got the Black Bean patty on white bread with pepper jack cheese, lettuce, onion, tomatoes, pickles and Dijon (toasted, because hot's better). I saw that someone else thinks that these are the Morning Star black bean patties - that I can't really comment on because I've never had the Morning Star...BUT, I thought that it was a delcicious sandwich and I think we have to give them credit for the right amount of black bean, delicious cheese (and pepper jack is usually not my favorite), lettuce, etc. It came out hot and I thought the bread was delicious! Not too bready (i.e. very thick bun), but just right and tasted fresh. I am really looking forward to returning and trying something different! I must say that I walked in a little embarrassed because I was confused by the paper bag options until I realized that there are different paper bags for "Veggie, Meat, Chicken, Turkey, etc." However, I did not feel rushed, and the final product did not disappoint. read more

First discovered this place in Iowa City about 4 years ago. So happy that they are now in the loop close to the office. The staff is friendly and helpful - the sandwiches taste great and it is a nice change of pace from the other sub places around town. read more

I came across Which Wich while I was in the Loop with a friend before going to a Blackhawks game, and in need of a quick, delicious dinner. What I fell in love with was the ordering concept--grab a bag from one of several types of sandwiches, and go from there. One thing I sort of dread about some other sub sandwich places is how tedious the ordering process can be "I want this... on this... with that..... and that... no, not that... yes toasted... a little of-- no, not that... that's it." And quite frankly, it's one reason I don't go to some of these places all that often--especially Subway. Being that it was atfer 5pm on a Friday, the place was practically dead, but very comfy. Friendly, quick service, too, and a flavor of locality with kids' drawings. Great location: located in the "basement level" of Block 37, next to the entrance to the Red Line station (the Blue Line entrance is up the hall). The price was definitely reasonable. read more

Just ordered a breakfast sandwich from this place via uber eats. Not going to complain that it was cold when I got it, my issue is that the sandwich was horrible. I was very surprised that they used the fake eggs. I hate fake eggs! I've never had a breakfast sandwich from a sub shop that didn't use real, scrambled eggs. Eggs tasted very spongy and gross. Previous to this experience I heard only good things...maybe they should stick to lunch sandwiches. What a let down, especially since the sandwich cost me $15 read more
