I love the florentine omelet at the Kings Valley Diner on Ulster Avenue. How can you not like a diner that serves their toast already buttered? I don't eat this kind of breakfast everyday, but when you are in the mood for a good diner breakfast, this is a great place to go in Kingston! Their salmon benedict is really good too!
