Food: pretty decent. You can tell everything is fresh and made to order. I had the pulled chicken tacos and the guac on it was very good. Reasonably priced and it seems like everything comes with freshly made chips. Which rock.
Service: Meh. Our server was very polite and nice- but did not know how to handle her time. My wife and I weren't in a hurry to be anywhere or anything- but our waitress took so long to get our check and bring some of our food.
Environment: best part about Sweet Melissa's. AWESOME room and cool look to the place. Light fixtures and bar just looked cool. There were a lot of crumbs and good left over under the tables. Kinda nasty.
Overall: I'd go back! But don't plan on being in a hurry!
