Bear or not, the Lone Bone (er . . .Star) is the best in SF. Great guys, fabulous bartenders (Bobby is the nicest guy around, Louie should be a stand-up comic, and Jimmy is a sweetheart), and wonderful music (how many bars do you know play Donovan's "Sunshine Superman"?). Sunday beer bust (4-8) is a must, but Saturday's beer bust (3-7) ain't bad either. Another "don't miss" is Bobby's Xmas Toys for Tots night. It'll warm your heart to see 240-pound bears bring in Barbie dolls for poor kids. The only bummer is when the rainy season comes and they have to put that damn awning up over the patio.
Pros: men, men, beer
