This Lincoln Park spot is a hole-in-the-wall gay hangout with celebrity pop-ups arranged around the small, dark room, a fully stocked bar and a porn video collection. "This is not an in-your-face bar," says Steve, the amiable daytime bartender, about the no-windows, no-dancing place. ''We have some men come in who are married who are not out of the closet. We're not out for guppies (gay yuppies).'' The free house poster is a cult trade item. ''When I was on the road, I saw the Manhandler poster scattered all over the place,'' says Steve. Asked the best way to describe the bar, he says, ''I want something about conversation. I want something about 'good times' without saying 'a good times, conversation bar.' ''
