Like Sherry said, go there en drab first if you can. Even if it is a gay place. Do a little research to make sure it is in a (reasonably) safe neighborhood, if not, don't go there. Much safer to go in daylight hours than at night, especially alone. If you don't want attention, even better during the day when there will be less people.
You can order a soda or a cup of coffee or something. And if you are driving, that is an excellent idea, a single drop of alcohol on your breath is a license for the police to make you get out and walk the line and all of that, not something I ever, ever want to experience.
