Smashburger is the bomb! This location is extremely friendly and the food is always hot and delicious. They never get the order wrong, which is a big deal to us. The smash fries are DELICIOUS! The shakes are good and they come in the glass shake thing with the extra in the metal maker thing--very old school. We go here... More

First off, I appreciated the service here. I thought the two people working the front of the house were very friendly and informative. It was my first visit and they were very helpful. I thought the burgers were quite tasty. My boys and I split the BBQ Bacon Cheddar Smash and the Buffalo Smash. Both burgers were crispy on the... More

It has been a year since I last visited. Had the Harvest Salad...excellent (maybe a little too much blue cheese). Fresh Tea. Reason tab..less than $9. Manager checked with us twice to make sure we were satisfied! Nice touch.

My first time at Smash burger had heard good things about the place so I could not resist when I saw it. Upscale burger place good quality fish ingredients. Numerous choices of hamburger or chicken sandwiches. My personal choice was the bacon avocado at first impression looked a little bit small. But after consumption it was very adequate. Went for...

Fantastic burgers, fries and shakes served dine-in or carry-out. Yes, it was a little expensive for "fast food," but the ingredients were all obviously high-quality and everything was delicious. I won't go back every time I'm looking for burgers, but I certainly will return once in a while for a great and quick meal.

A ridiculous amount of salt on the seasoned fries. I mean over the top insane-- nobody could like them like this. OK so why only two stars? Well apart from the fries-- which were very expensive (for about $3.50 I expected enough to share-- still not sure if I got the large that I paid for. The point was moot... More

This was my second visit here. Good burgers and fries. Tried the spicy buffalo fries - really good - spicy for sure. Probably overdose of catsup/mustard - would ask to hold back next time. Tried a milk shake this time, so did my friend. Neither were great. Definitely not worth the price. Service was fast and very friendly. I probably... More

Nice big juicy burgers. Tons to select from. You can also do a create your own burger option. The fries are great with a side of there famous smash sauce. Went with a group of three and we all had a different burger and they were all great. We will be back again.

Our group of five adults had a variety of the burgers on the menu, and not a one of us was disappointed! Probably one of the best burgers I've ever had (the BBQ bacon cheddar) and I would give this place 5 stars but the fries were just meh. Shakes are half price on the weekends, so I busted my... More
