I've tried their smashchicken and smashburger, but love their smashfries. Their burgers are tasty, but as a sucker for yummy fries... I go here mainly for those when I'm craving something salty and well, not so good for you - but definitely tasty!
They're usually pretty steady business wise, even in the off hours, but they manage to maintain a clean location that has pretty speedy service. I'd have to say though that with a decent amount of competition close by (primarily being Zinburger), they still hold their own. I think next time I'll try their salad instead though.
