What can you say about an old school institution where you can order your burger in the most epic of menu offerings, and have it arrive perfectly and with a friendly smile? They are awesome! If you dare, try the rest of their menu... it's nostalgic and satisfying! Sometimes parking can be difficult, but there is plenty around back. Btw, save room for dessert! LoL! read more

really good service, the waitress we had was super kind. the Oreo milkshake is really good, i also tried the banana one but find it too sweet. i got the mushroom cheeseburger and it was amazing. I also got onion rings and fries, both pretty good too. limited seating inside but not too busy so we were quickly seated. overall nice burger spot, I would go again if in the area. read more

Don't come late at night after 2am m. The service is wack. They don't take orders in order of people walking in. We waited 20mins then see waiter go right away take someone else order that just walked in not even couple mins sitting at table. Smh. I had to call the guy out on it. Really came because the videos online saying food was fire and open 24 hrs. No hello nothing to us but other groups. read more

Got the double bacon cheese burger and it's probably the best you can get anywhere. They're super generous with the thick cut bacon and they literally wrap the patty in the bacon like nothing I've ever seen before. The amount of care they put into my burger genuinely impressed me. And they're open 24/7. REMARKABLE! read more

They charge $$2 for pickles on a burger. I have never heard of this before. Last time I eat here shame cause I used to frequent this restaurant now I'll boycott cause of the pickle charge. I'm a pickle fanatic so this is the last time I'll be here read more

Came late night after some pool and beers. This is an old school diner, the type you see in the movies. Breakfast, burgers, shakes and the daily specials. I had the Double Bacon and Mushroom Cheeseburger, which our server highly recommended. Our server was really friendly and enthusiastic. Food came out pretty fast, Burger was huge, a bit sloppy but expected with the amount of bacon and mushrooms piled on top of two 1/4 patties. Burger was really good, needed some seasoning but the saltiness of the thick cut bacon made up for it. Price seemed a little steep at $17, for just the burger. Overall not bad for a late night meal. read more

1/4 Lb Big Burger - Double Bacon and Mushroom Cheeseburger - Burgers Near Me - Martinez, California

Stopped by 1/4 Lb Big Burger and tried the breakfast burrito, it definitely satisfied the craving. It was packed, hearty, and full of flavor with a good balance of eggs, meat, and fillings in every bite. The tortilla was nicely grilled and held everything together without falling apart. It's simple comfort food done right. The classic diner vibe adds to the experience, and service was quick and friendly. Being open 24/7 is a big plus. I'll be back to try more from the menu. read more

This is the best diner is the Bay Area!! The best food and atmosphere and it's super reasonably priced read more

Wow I am so disappointed because I always come here but this time the service was off. I repeatedly said what I wanted and they ended giving me something else and the French fries were very stiff and no flavor. The cashier was very accommodating and understanding because the food this time tasted different but the waitress seems like she was rushing and not really checking on us and paying attention. She didn't even asked if the food was good. Didn't even the hand us the check. All she asked are you done? So she can pick up the dishes. read more

They were not very busy when we went, so service was quick. I had the hamburger sliders, which had three (I think) mini burgers & my wife the quarter pounder. Both were delicious & filling. The ambiance was typical diner style. We will go again when we get hungry for burgers... read more

WHAT A HIDDEN GEM. It may not look like much when you walk in, but it's PERFECT old school local diner fare. Places like this just don't exist anymore. The patty melts. The fries. The shakes. The breakfasts. Pure comfort food. Fun to sit at the counter and watch the guy at the grill if it's busy too. A maestro performing. The waitresses are always super friendly and nice as well. read more

Been going here for 30 years. No matter what time of day you can get a solid meal. Burgers and fries have forever been A1. Grew up going to the Brentwood one, then Clayton and now Martinez. read more

I loved this place. Old school no frills diner. A real throw back with a good burger and great milkshakes! Counter service!

Food is not the same as use to be, not going back anytime soon . Asked for crispy bacon got rubbery bacon and asked for sourdough toast and got wheat instead and asked for eggs over easy and got scrambled instead. And the eggs were not even cooked properly read more

I've been here about 5-6 times so far and have not been disappointed at all. The first few times I had the bacon cheeseburger meal and it was definitely good and hit the spot. The service is always good and they're fast too. I tried the 3 egg breakfast this last time and let's just say I went back for more cuz it was that good. Super cute little diner with tons milkshake flavors too. read more

1/4 Lb Big Burger - Double Bacon Cheeseburger.. yummy! - Burgers Near Me - Martinez, California

I forget about this place but came here a few times for a really late night meal. Came by last Saturday night and the employee was really friendly, patient and welcoming. Patrons had smiles on their faces. We had a mushroom burger and double bacon mushroom burger. Onion rings (to die for) and fries were delicious. We demolished our meals. I would go here all the time, but I live a bit far. Thank you for staying open late and serving the hungry community read more

The burgers here a good, but everything else I have ordered is low quality food. Biscuits and gravy special, I was hoping for a winner, but it was barely edible. Chewy eggs, weird looking and tasting gravy, hard biscuits, and half cooked bacon. Fries are usually undercooked or overcooked as well. I simply go for the burgers at this point. Just no lettuce on there, it's shredded. And the milkshakes are decent. I was hoping for better food since it's one of the only late night spots, but at least I know where to grab a late night burger. read more

Horrible Definitely won't be going back again a waste of 24 dollars should have just went to super duper burger would have been way better and cheaper not saying 24 dollars is a lot but it's my money and I'm putting my trust in a food place that should do whatever it takes to make sure their customers that they serve are happy which I am not happy at all. So don't waste your time and money go elsewhere trust me. And let me go little bit into detail so the hamburger bun was very soggy and the bacon was so salty. now I know bacon is salty already but this bacon was so salty I said for get it and trash the whole hamburger and the french fries OMG was under cooked and soggy as well just horrible hopefully this helps someone thanks for reading. read more

Working in the area for many years, there are not that many places to eat late at night, especially in Martinez. 1/4 burger is finally back to being 24/7 for the first time since the pandemic. Some people will complain about the prices increasing but hasn't every establishment? Plus their food is always cooked to order and way better than choosing a fast food spot. My bacon cheeseburger combo here is only a few dollars more than any fast food spot, and again working nights it's the perfect place to get food that's hot and fresh. Their bacon burger literally has two huge strips that wrap around the entire burger. They do not skimp on their ingredients either. It's a no frills, consistent place every time I've gone. I call ahead every time, and have the food just about ready when I get there. read more

Can't believe I've never reviewed before, since I've been eating here for 20 years. The burgers, patty melts, fries & onion rings are really good, but my usual is bacon & eggs. James cooks everything perfectly usual hours are 10pm-6am) but the other cooks are good too. The pancakes are huge, plate size. I often get some to go & heat up the next day. They reheat really well. All the food looks good and I've never heard anyone complain about food or service. The reason I deducted a star is because the prices are getting so high that it's cheaper to drive to Digger's for lunch. I understand prices need to be high enough to cover increased grocery prices and I hope higher wages, along with all the other higher costs today. Nothing has been spent on updating the building, inside or out, since I've been going. lol. The charm of the bar stool that's been broken for as long as I can remember, the window seals so dirty, they've never seen a cleaning product. lol. It would make me feel better to see the place cleaned up a bit. One very positive thing is that I feel very comfortable going here alone. As an older woman that's very important to me. If harassed, I'm pretty sure James would come flying over the counter to protect me, but people who come here are always friendly and respectful of others. read more

Picked up lunch for the crew. Never been here before, so we gave it a shot. It was about 11 am and they were busy enough. When we walked in, most of the patrons were eating breakfast, but we came for burgers. It's a nice place with just enough parking. Not too loud inside, but your usual small restaurant expectations. We ordered 6 cheeseburgers and six fries. It came out quick enough, and off we went to the work site, which was 20 minutes away. Showed up and passed out the burgers. You would have expected the bun to be a little soggy due to the size of the burger, which was huge, but they held up all the way to the end. A definite plus. The serving of fries was also pretty decent, and they were also tasty. Overall, they were definitely worth it. read more

This is a great place I think it's open 24 hours a day too. Portions they serve are great. The food is very tasty. The only problem I had is that when they gave me the biscuits and gravy the guy put the gravy on and set the plate aside. And I got the meal it was not hot. But everything was tasty in fact I think that they gave me too much. Coffee was nice and they give you large portions of creamer unlike other restaurants will give you a small sample. That way you don't have to ask for more. The staff was friendly I've been here a couple other times before and went definitely recommend it it's a little difficult hard to find. And if you didn't know it was there you wouldn't know it was there but if you're in Martinez I recommend this place highly read more

Tried 1/4 Lb Big Burger for the first time with my dad and had a great experience! I got a cheeseburger, fries, and a Sprite--everything was super tasty. The place has a cute 90s vibe that made it feel really cozy and fun. Definitely recommend if you're in the mood for a good burger and some nostalgic charm! read more

Well it's still bussin. It's almost inflation proof. The waiter came by with coffee like every five minutes. Didn't even have to ask. Food was just bussin, got the three egg lingiça breakfast with pancake and yeah, bussin. Very unassuming exterior kinda diner style interior. Great breakfast. read more

Just picked up my order. I used to come to this place all the time a couple of years ago but it's definitely not the same. Prices have gone way up. They don't match their website. Food is very mediocre. Very freezer burnt and dry. Half of our mozzarella sticks were empty inside. Milkshakes are super artificial. For the price I recommend else where. read more

Delicious, consistent local joint thats open til the late hours for after a night of bad decisions or just cravings. They call it tweaker burger but I don't think I've seen one there yet. Maybe the tweakers were the friends we made along the way read more

I don't know what they do to their burgers, but they are so favorable! Plus, I like how they bring our hot fresh fries first and then your burger read more

Fast, delicious food with absolutely no frills and solid service. Menu is a bit confusing - most things are very cheap, but some things are oddly expensive. Coffee surprised me in particular. But overall the value here is very good. Onion rings are battered as opposed to breaded - definitely my favorite style. Mushroom cheeseburger was excellent. Steak sandwich was way better than I expected for the price. Overall a really solid stop if you're driving out on 680. read more

Nice hole-in-the-wall diner! I do think they overcharge me for not ordering combos, but for a quick burger and fries, or a side of hashbrowns, they know what they are doing! I wouldn't come here for a salad, but a greasy spoon meal? Hell yes lol read more

Sadly good ol 1/4lb Big Burger has really gone way downhill... The good first: Milkshakes are still excellent, the burger was still decent. The bad: the fries and onion rings literally had no salt on them. How do you pull a fried side like that from the frier without salting them? Sure, I can add salt, but everyone knows it doesn't stick right unless you do it right out of the frier. Additionally, the fries were soft. The burger had WAY too much mustard. Now for the worst part of all... The prices have jumped SUBSTANTIALLY. Literally the bacon cheeseburger special went up over 40%. I have been eating here for years, so I was shocked to hear my total. $15 for a bacon cheeseburger meal makes this place no longer the cheap hole in the wall. It's also not as good. So if it's not cheap, nor that good... I'll just go elsewhere. Copper skillet has an incredible bacon cheeseburger meal, for basically the same price... read more
