Great late night menu with not the usual Denny's selection. I believe it starts after 10 but it could be 11, I forget what time we got there.
My friend and I were working on a project and stayed for hours and they didn't mind at all. They just made sure to check on us and get us more drinks. It was the right environment for getting work done and still having a good time.
And yes open 24 hours on the north west side of town is a big plus in my book.
