Oh No!!! I am wrong on my guess about a home game.
How about the name of the restaurant? Do we have a new illegal? I'm excited.

I guessed home game because of the 3 initials.
In the early 70's I had chips made for a poker game they had a B, E, G on them.
Brownie, Eddie, and Gene. I forget the order of the BEG on the chips. They were all lost in a raid.
