Located just off busy Davie Street in the West End, the Jupiter Cafe combines a post-apocalyptic industrial look with lounge chic. Black ceilings, exposed pipes, and roof struts mix surprisingly well with chandeliers, velvet curtains, and plush chairs. More important, the Jupiter is open late (till 4am some nights). True, it can be a challenge to flag down your waiter, but that gives you more time to scope out the crowd: gay and straight, funky and preppy, casual and dressed to kill. A huge outdoor patio provides a pleasant refuge from the street, but on colder nights it's the exclusive domain of die-hard smokers. The menu -- burgers, pastas, and pizzas -- is largely decorative.
