Staying in a Magnificent Mile hotel and looking for a late-night libation? Martini Ranch serves 40 different versions of its namesake cocktail until 4am during the week, attracting bar and nightlife insiders -- and a fair share of insomniacs. The Western theme is subtle (paintings of Roy Rogers and other cowpoke art) and the seating is minimal (come early to snag one of the four red booths), but fans swear by the chocolate martini, and the pop-rock soundtrack keeps the energy level high. If the crowded bar scene is too much, chill out at the pool table in the back room, or settle down at one of the tables in the heated beer garden.
