"Big Grin is a burger joint offering three-and-a-half ounce Pat LaFrieda beef patties, an Impossible Burger, cold lobster rolls, hot dogs, crinkle-cut french fries, duck-fat waffle hash browns, and desserts. The cheeseburger pairs well with a 'pickle minitini.'" - Erika Adams

Food: This place has one of the best smashed burgers, super juicy, and their crinkly fries are lightly seasoned, still crispy even when they got slightly cold after I finished eating the burger. Their fries are waaaaayyyy better than the sad soggy sorry fries from ShakeShack. I do have a suggestion, could you please bring back the sesame seeds buns, the last 4 times my burger was made with a different bun no sesame seeds :( Service: The lady who works there always provides exceptional service, she always keeps a positive attitude even when some of their customers were being impatient and rude to her. She’s amazing, please give her a raise!!!!

Burger was reasonably priced and taste was good. Didn’t love the tater tots/hash browns because they didn’t have a lot of taste and were super greasy, but overall it met expectations for what I was expecting. Comparable to ShakeShack.

Just a typical mediocre smash burger. Honestly shake shak is much better and it’s cheaper. The olive oil hash brown was swimming in oil. It made my stomach hurt. Wouldn’t recommend.

I love the burgers from this place but it is a bit pricey. Great place to go for lunch during work. However, there can be quite a line, so I recommend to order ahead of time if you are in a time crunch. I got the big bacon burger and everything was just so good (bacon, onion, burger).
