We were passing through and stumbled upon this place and OMG best smash burger we have ever had. Absolutely delicious!! These burgers are big on flavor and size so come with an appetite. The fries were fresh, hot & perfectly crispy. They did not disappoint.

I love this place! Service is amazing! The burgers are
To die for!!! And usually the garlic fries are the best part! But the few times I’ve done there the fries were all hard and over cooked tasting. Usually they’re soft and even better the next day. But the past 2 times within 30 minutes I couldn’t even chew the fries because of how hard they were, I couldn’t even eat them later for snack or the next day for lunch. I was pretty disappointed there since that’s...

We found this place when searching for some great food after our son's week long wrestling camp! We were surprised to see it was a food truck and not a brick and mortar place but it was a happy surprise with the lay out, experience, and other food trucks around with the community style dining hall! We had a fun experience and the loaded fries were all great! My son inhaled his kids cheeseburger and fires aswell! Great place! We will be back if we are ever in the area again!
