“ Grew up eating this place! Wonderful service and great food! Portions are large and fries are fresh. The Michael's ice cream especially in a shake is a must to get with your burger. Love getting all that and dinning in on a hot day with indoor/outdoor layout. Plus the food is made right in front of you so you can see all the action. I will definitely be back again! ”

“ This is my friend's favorite burger spot, in the area. The burgers are a good size and very flavorful. If ordering through online the prices are slightly different, by $1. I don't think I've ever been disappointed with their food, but...it is interesting that their menu mentions for some of the burgers that certain sides come WITH the order, which you would think is part of the price. Yes, it is only $1 for the side, even tho it says it comes with it, and you do get a good portion, I just think it's weird that it says "with." I would definitely go back and at least now I know that whatever side u get with it, fries, onion rings, etc..it will be +$1. I guess that is still better than paying the full side price. ”

“ We three popped in here around 8ish, ordered two burgers and one cheese steak, it was SOOOOOOO GOOD!!! The staff was so pleasant and cheery. It's so nice to eat at a place where it doesn't seem like the staff hates their job and would rather be anywhere else! They might feel that way here, but you certainly can't tell from their pleasant and positive attitudes! It was also very clean and food was ready FAST! I'm super impressed with this place and will definitely be back next time I'm in the area. ”

“ Big Mouth burger is my go-to burger place and I'm glad they've survived the pandemic. Love the flavor of the char! Peruse the menu board, order at the cashier's station. The cashiers are friendly and helpful with any questions on the menu. Pay then grab a table or wait for your takeout. Plenty of seating inside, as well as a few tables right outside. Their takeout has been fine except a few times. My latest order was their juicy TURKEY BURGER with side salad, no dressing. But lately when I order a side salad salad, I unpack my order to find the salad dressed. Another reason I don't order it the salad dressed is it leaks from the container gets all over the bag. Please note dressing on the side helps a lot! Their latest creation has made it from occasional special to the regular main menu board - JALAPEÑO BURGER! The jalapeño burger has Jalapeño Ailoi, Pepper jack cheese, bacon, fresh grilled Jalapeño, lettuce, tomato and red onions w/a side of french fries. This is a really well put together burger especially with the fresh jalapeños! If trying to be healthy I'll sub in a Turkey burger for beef, and a side salad for the fries. Their milk shakes, made with Mitchell's vanilla, chocolate, or strawberry ice cream, is the old-school real deal and a real treat to end your burger feast! There are a variety of burgers to eat your way through the menu like The Giants Burger, The 49er, The Warriors Burger, Salmon Burger, Fried Chicken Sandwich, or healthier options like The Falafel Birger, The Garden Burger. Or sub out the beef in any of the burgers with beyond or Turkey patty. Lots of options. Have it your way! Lol! Head to Big Mouth Burger when you're drooling for juicy burger with a flavorful char! ”

“ My brother told me I've gotta try Big Mouth for their burgers and he was spot on! I had the half pound burger medium rare with pepper jack and fries. By brother had the same burger on a French roll. The burgers were delicious. The steak cut fries were perfectly crisp on the outside and temperature hot on the inside. The service was friendly. They had a couple televisions and lots of great 49er / Warriors/ Giants memorabilia on the walls. I'll definitely be back:) ”

“ Great burgers cooked to perfection. This place offers many options besides burgers. From sweet potato fries to the fresh coleslaw, the flavors are outstanding. Plenty of indoor and outdoor seating is available. Fast friendly service. ”

“ Absolutely Amazing! Check this place out! Hidden gem for sure! I got the Pepper Steak and it was sooo yummy! I recommend hands down! ”

“ Nice neighborhood burger shop in the e Bayhill shopping center in South San Francisco. Plenty of parking. The inside feels like a diner, plenty of seats. You order at the counter and they bring out the food to you. The service was welcoming and friendly On my visit ordered their name sake big mouth burger and it lives up to the name. Burgers are cooked to order so it takes a little bit but that makes it juicier and tastier imo. I added cheese and bacon and it came out great. Burger was juicy and not dry, sesame seed bun was warm soft and toasted, lettuce tomato onion were all fresh. Combined All together a solid filling burger. The fries are a thicker cut but still was crispy. Overall I liked this place, burger was solid. ”

“ I fell in love with the design. Yeah, that's what's so appealing about spending $15 on a single burger. But maybe, uh, maybe it's not just that... The menu style at this place is really creative and well thought out. You'll be happy to buy a Warriors burger without even looking at the ingredient list. Okay, I'm kidding. But it's hard to argue with that. The place itself didn't look very clean and while we were waiting for our order, I sat on a seat that was unpleasantly sticky. Of course I didn't like it, who would? About the food I can say that the fries were not crispy at all, which made me sad, but my husband likes their burgers, which is fair enough - they're not bad. All in all, I'm giving them 4 stars for now but was considering to put 3... I think this way because the price has to meet all the criteria, not just a few. ”
