I've been here for dinner multiple times now, and have yet to be disappointed (not that I expect to!). The staff is very friendly and service is fast. I think I've been in and out in less than an hour when we had a show to catch nearby!
The food is delicious and there are plenty of vegetarian/vegan options to choose from. I've had the mac and cheese at least twice and absolutely love it!
The ambiance here is very home-y and low key - what you'd expect from a family-owned diner. I love it.
