The room is small, and it's usually full, whether it's the Wednesday-night poetry reading (sometimes erotic) or the live local jazz on every other night (always erotic). But whatever your fetish, Troy's on the Park can probably quench your thirst. There are 30 martinis to choose from -- owner Troy Williams calls them the "Troy Quickies" or "Troy Specialties," depending -- and there are fine-dining establishments up and down the street for before and after. Just a year old this month (October), Troy's showcases local jazz artists like the Sid Rodway Quartet and the T.C. Quintet, and the patrons, a multicultural, multiage crowd, understand the etiquette of a true listening room.
