At Centaur, the martini is monarch. The menu of seasonally changing cocktails ($9 each, $5 during happy hour) leaves no taste unexplored. The toasted-almond martini swizzles together vanilla, almonds, cocoa, and cinnamon, while the Detroiter uses hometown-hero Vernors ginger ale with splashes of vanilla vodka and spiced rum. Secret agents on the lam after a botched attempt to blow up a supervillain's volcano lair can unwind with the .007 martini's mix of vodka, gin, strawberry, and basil while awaiting further instructions from contacts "Hansel and Gretel," who are enjoying a gingerbread-flavored martini at the other end of the bar. In addition to an extensive selection of beers and wines, Centaur also offers a menu of gourmet small plates for stomachs not quite satisfied by toothpicked olives. Try an ounce of Sevruga caviar ($50), Maryland crab cakes with lobster cream sauce ($10), or three gourmet mini-burgers ($6).
