Tough Guy Bar

These tough guys are so hard I can feeeeeeel it.

The dirty, dimly-lit tavern with all the big brutes in it. To show that they're hard, they do hard things like arm wrestle, play Russian roulette, the hand-knife game, and beat other guys up for the hell of it. When the Hero or Main walks in, they all turn their heads and stare the newcomer down for intimidation points. The bartender won't be as hard as everyone else, but he might have a gun just in case some guy thinks it'd be funny to get too hard and shoot him when he's off guard.
