Owner, hostess and wait staff are super friendly! We come almost every weekend for breakfast and love it. The feta and spinach omelet is superb!Upvote6Downvote
Terrance BradshawJune 23, 2017The food is great, I usually come for breakfast and dinner. I always get the steak and eggs for breakfast, some of the waitresses even know what I want before I tell them. Love this placeUpvote1Downvote

John Obey-AmoytAugust 13, 2015Food is good. The service is terrible sat there for 15 before anyone brought a menu. Then had to wait another 10 minutes before anyone took our order. Happened 2x all white customers served first.UpvoteDownvote

- Shannon RyanDecember 4, 2011We are always sat in the same super tight spot, with the same waitress who goes to everyone else before my family even if we have sat here without drinks for easy 20 mins. Food comes out cold tooUpvoteDownvote1
