None that i know of... whats the worst that can happen though? you and your friends have to go to a differant bar? carry concealed and you shouldnt have a problem
of course, if you go to the sh*tty kittey, you will need a gun. the last time i was in there, these skinheads (SS patches and all) broke a bottle over this dude's head and then stomped him.
on second thought, just pop your collar and drink jaegerbombs at chumleys.
