many years ago, i commuted regularly, on a shuttle that dropped me off at 24th & mission in san francisco. right in front of big mouth burgers. my group of co-workers/friends and i quickly established a tradition of going to get burgers on monday nights. we eventually expanded to include papalote, for burritos, also right near the shuttle stop. and thus, "b night" was born. let's just say, i ate a lot of burgers back then.
