Great ambiance! The service was a little slow, but the meal was made to perfection. Chicken wings were the star of the show! Seasoned perfectly and tasty, even without sauce.. A must try if you're looking for a good Americanized meal. read more

We were craving a good burger, and Burger & Mayo Lab delivered! I made an online reservation close to opening time during the weekday. There weren't many diners there during that time. There's plenty of seating space available. Service was good and pretty prompt. For starters, we ordered the fish tacos. These were large and filling enough to have as a meal. I wanted to try the Fire Burger as seen on TicTok, but I was told that they no longer had it available. We ended up ordering the Smash Burgers as our entree. This burger was huge with 3 patties, but SOOO good! Juicy, cheesy, and seasoned well. I had to unhinge my jaw a couple of times after biting into this burger, LOL! read more

Saw this spot on TikTok and decided to check it out. I have mixed feelings overall but definitely some highlights! Service was amazing -- the staff was super friendly, attentive, and made sure we had everything we needed. Food came out quick too, which was a big plus. The vibe is very brunchy/artsy with neon lights and murals, super cute for pictures. We started with the loaded fries with pork belly and the truffle mac & cheese with fried chicken. Both were SO good. The mac & cheese was creamy and flavorful, and the crispy chicken on top gave it the perfect balance (not an overwhelming truffle taste either). The loaded fries were tasty, cheesy, and I actually liked the raw onion for a fresh crunch. Huge portions too, perfect for sharing. For mains, we tried the mini sliders, volcano burger, smash burger, and a cocktail. The sliders were a win -- tasty and just the right size. The volcano burger was the only letdown... the patty was overcooked/burnt and not hot, and the cheese was kind of runny. The smash burger on the other hand was HUGE (three patties!) so if you don't eat much it might be too much, but definitely filling. Overall: amazing service, fun vibe, appetizers were the star of the show, and while some of the burgers fell short, I might come back to try more of the menu. It definitely feels more like an American/touristy spot than a local one, so just keep that in mind. read more

Visited here for dinner on my second day in Puerto Rico. I had high hopes and picked it based off recommendations from TikTok. The burger was okay and my husband enjoyed his. Their fries are really skinny and not the kind my husband prefers but he still said that they were solid. I had the onion rings. As an onion ring connoisseur, these were horrible. Not crispy at all very chewy and the batter of tasted like hush puppies. Not somewhere that I would visit twice.. read more

Greatest place I've been can't beat prices and food quality better then places charging out high prices will come here every time in pr!!!!

The food was great. The service was great and inside is definitely Instagram worthy. I would've given this place a five star rating. If I went at night I think it would've been more of a vibe and I could've tasted the drinks, but we went during the daytime so it was pretty empty. There's so many options to choose from them on the menu which I really enjoyed. read more

Stay away from this business unless you're willing to risk severe food poisoning. I ordered a veggie burger with onion rings and I'm not sure what went wrong but a few hours after dinner I was violently sick from this. There is something severely wrong with this restaurants cleanliness or food practices. The food is also very pricy and poor service they were clearly understaffed. The ambiance is really cool and instagrammable but not worth getting sick for. read more

The A/C was up very high. It was very cold inside the small restaurant. They have a VIP area off to the side that peaked our curiosity. This place is ridiculously slow. We only order burgers with fries and it took close to 45 minutes for our food to arrive to our table. My Lab Burger was dry and hard and my fries were cold. The fries were seasoned well and probably would have been great had they been hot or even warm. Our server Ashley was sweet. No complaints there. read more

I had asked for my "smash" burger to be on a brioche bun instead of the croissant. my waiteess said "they are out of buns and everyone's burger will be coming on croissants" 40 minutes later and burger were served on buns. I asked why they have buns when she specifically said they were out. she replied with "the bun man just came to drop off buns", keep in mind it was 8p when we got our food. I then asked for the mayo-bbq which she told me she was out of but said they have bbq sauce. never given sauces in the tubs like advertised. instead of offering to make it right, she just said "do you want a bun or not...I did not lie to you when I said we didn't have buns" - after that staff refused to talk to me. I asked for my meal to be comped since I didn't eat it and no one gave me an answer until the check came to pay. my waitress did not acknowledge me and proceeded to walk away. my friends were enjoying their meals and a few bites in she came over and asked if they wanted boxes, we had only had our food for about 5 minutes and felt very rushed. unfortunately very cool idea and concept, horrible atmosphere and service. Rooftop is next door, highly highly recommend that, great food, great service, and all around better. read more

My party of 5 waited for 45 minutes. I went inside and told the hostess our wait time is up. When I told her, she told me she couldn't seat us because they're understaffed. There were 3 tables available but the hostess told us she couldn't sit anyone because the food is taking 1 hour to come out. So overall that's 1 hour and 45 minutes wasted with no food. The hostess should've told us they're not taking any more customers if they're short staffed. We ended up going somewhere else because of their poor communication. read more

The restaurant is so cool! The drinks are cooky and so instagrammable. I only took a video and can't get a good enough screenshot, but Le Formula was STRONG but really lovely. Had the fish tacos with a side of fries. The fries came out inconsistent throughout my party; some were VERY crispy, some weren't - wish they did better with that cause some were borderline burnt. But I did like the fish tacos. Their burgers also look really good. And it's sooo funny how they give you ketchup in syringes definitely check it out! read more

Walked to this cute burger spot in San Juan. Waited outside in their waiting area (that had great photo opportunities) for about 15 minutes. They sat my husband and I soon after that. Our waiter saw that the original table we were seated at was damaged so he offered to move us. We both got build your own burger with sides. I got the papas aioli and hubby got Orion rings that's also came with aioli. Soooo good! The burgers were huge...I didn't finish mine. They also have shakes, drinks, nachos and more. Would def recommend if you're ever in San Juan. read more

Updated review: I went back to this spot to attempt to show my boyfriend on a Saturday night around dinner time looking for some drinks and an appetizer. When asking for just that, the hostess replied "let me go ask if that's allowed" then came back outside and told us the restaurant was closed when it definitely wasn't. Although I look like a tourist, I am a local. I would've rather her response been "you have to order a meal in order to get a table". A little disappointed... better off coming here during the week to prevent getting turned away! read more

This place is definitely a hidden gem, it is on a business trip so be very mindful the food is phenomenal they do close the door is one hour before closing time so be sure to be there early the service is not the absolute greatest I would give them a six out of 10 the server tried to tell us what to order because the kitchen was closing in an hour and she took a long time to come back to attend to us, we felt like she was trying to make the time pass by that we we couldn't order the items we wanted...we still order what we wanted anyway and everything came out great it's a beautiful scenery for pictures it's definitely an experience read more

Such a cute and Instagrammable spot for tourists and PR natives! This was conveniently walking distance from the AirBnb I was staying at. We had to click on a buzzard to be let in, which was interesting. I believe we needed to show our vaccination cards (not sure). We were seated quickly and our waiter was very welcoming and nice. Some of them do speak English for those who don't know Spanish (me). We ordered our cool nitrogen drinks. Half of us ordered the "La Fórmula" and "La Solución." Both drinks were fruity and good. I love that they put candy in them. They also have a big size of each for $25, if you want to share as a group. My drink (La Fórmula) was kinda sour which I liked. For our meals we mostly all had a Lab Burger and fries. My one friend got the Truffle Mac and Cheese and she enjoyed it. As for the burger it was not the best. I don't think there was much seasoning because it definitely had more of a ground beef taste. I had to use a lot of ketchup on it for more taste. The fries were great! Prices are not too crazy. We loved our experience here and took so many cute photos! read more

Well i came here as a tourist visiting food . Me and my friends arrived at 9:02 the doors were locked and the bartenders looked at us and didn't come tell us anything .. we knocked they said the kitchen was closed but the restaurant didn't close until 10 so unfortunately i didn't get to try the food because the workers were eager to leave early tonight read more

Seen a post on Instagram and decided to get lunch during my PR visit. I love the cute swings outside. I wanted to try the quesadilla but they were out. I got the bacon burger with cheese dipping sauce on the side. Good choice although I was sad they were out of the rainbow bread. Our waitress really took her time explaining the menu and what's popular which was really nice. FYI The front door was locked so we had to knock and wait outside to be let in. read more

Bottom line. One of the best burgers I have had anywhere. The eating experience was awesome. The beers where super cold. Service was not up to the standard of the food. It was a little slow it seemed because they appeared a bit disorganized. And, I don't think it's reasonable to deny a glass of ice tap water to clients if they ask for water. But the burger, the sauces and the sides where good enough to make up for it. I will be back. read more

I came to dine in with a couple of friends and the wait was ridiculously long. We arrived at 7pm and did not get seated till 8:20pm. Not only was the wait terrible but so was the service. After waiting to be seated we also had to wait to be attended by our waiter. The Waiters and the bartender were so slow. I ordered the Chicken Lab and they did not have all the ingredients available nor made any compromise for the inconvenience. I ordered water to drink but they don't provide any courtesy water so I went for a lemonade instead. All of my friends drinks arrived and my simple lemonade drink was no where to be found. My food came before my drink I waited another 20min and still no drink. I am a person who hardly ever complains but waiting almost 30min for a $5 lemonade is outrageous. I asked if it could be taken off my check and the staff was so quick to deny and were absolutely rude. Please DO NOT WASTE YOUR TIME AND MONEY this place is way over hyped. The only decent thing was that the actual restaurant itself was a very lovely place to take pictures. Definitely not a place for a large group due to wait and how slow the staff is. The food was mid. read more

Burger and Mayo Lab - Burgers Near Me - San Juan, Puerto Rico

Brand new spot that is still prepping for inside dining for now. They are famous on Instagram for their drinks and burgers. The rainbow burger was good but the bread was too dense. Perhaps the extra food coloring made it this way, I didn't quite enjoy the the bread. The fries were very well seasoned and was heavy on garlic on the thinner pieces of the wide cut fries. However, the fries that were served were not very many and they were soggy. This won't stop me from coming back again though. They are new and understandably will have some kinks in the beginning. Once they are fully open for inside dining I will def come back again to get the true full experience with hopefully some more crispier fries to boot. read more
