Went for diner tonight food was great service was poor. Worst part was the tip is added automatically when a group of 8 or more of 18%. That is fine when the server is prompt but it was not like they were under staffed. They need to step there game up a bit. I would try it again just the wife and I but currently would not recommend it to more than 2 people.
