My wife, daughter, and I stopped in for an early lunch on a Tuesday morning. Even though it was only about 11:00 a.m., the restaurant was very busy, but we didn't have to wait for a table. The server was very friendly and efficient. We got our food very quickly. The bread basket was a little disappointing (dry, sort of stale), so I wouldn't bother with that. Otherwise the food was excellent, and it was one of the better meals we've had in East Nashville (a neighborhood filled with very forgettable restaurants). The price for three with tip was about $40, so it isn't inexpensive. But, the atmosphere and food are good, and we came away feeling very positive about the experience. We've put this on our very short list for a return visit.
Marche is very popular, and the parking lot is a little tight. You may want to plan accordingly especially on the weekends.
