I walked in and it was the first time I had ever been to a Smashburger. The place was not too brightly lit (5 guys get a clue), had nice seats, it was clean and had a very good first impression. I had followed a young couple in and it was obvuious they were on a date so it was good enough for them to pick as a destination. Menu greeted me at he doorway so you could a have a look at it, proceeded forward to order and the wait staff was polite and nice. Definitely upscale from the competitors.
Food arrived quickly. I had read Yelp reviews, so was prepared and had the 1/3rd Smashburger, sweet potato smashfries and soda totalling just under $10.
Music was a little too loud in the dining room, the burger was tasty, but as soon as I raised it there was a puddle or juices that dropped out. It was fresh and I liked the generous veggies on it. The sweet potatoe fries were mystifying; didn't know whether to put ketchup on them or not. They also had an Italian herbal flavor (oregano, basil ?) and while tasty are not something I'd normally order.
Summary: Very nice place, good food, good ambience and just a tad out of the ordinary to be striking.
