Where // 2933 O'Donnell St.

Call // 410-563-5000

Web site // (it's owned by the same company)

Notable // The two most popular martinis are the Espresso Martini, a mix of vanilla vodka, Baileys Irish Cream, Kahlua and a splash of espresso, and the Ultimate Cosmo, made from Grey Goose Orange vodka, Cointreau and splashes of lime and cranberry juice.

Vibe // Here, the atmosphere can only go so far -- the rest all depends on the people. If a big crowd is into the music and on their feet dancing, you'll probably have a better time than if the place is empty.

Crowd // Typical for Canton Square: a mix of twenty- and thirtysomethings.

What to wear // You can get away with jeans and a button-down, but you'll also see people in black pants and gelled hair here.
