This is a public event that anyone is welcome to attend. Come and enjoy good food and good conversation!
As for Fat Willy's (per their website), "Fat Willy's is a family neighborhood bar and grill with a garage theme. Our menu features full flavor burgers, specialty dishes, with take out service available." From my experiencethe food is pretty good and the prices are very reasonable.
As for RAFT, we are a group of atheists, agnostic, non-believers of all types, so feel free to join and talk religion or politics or sports it doesn't matter to us! We just enjoy meeting new people and have a good time.
