The photos on the wall of the Avenue Grill date back to the '80s, but the feel of this bar dates back much further, to those classic cocktail lounges of the '30s and '40s. And you can taste that golden era in the martinis, which the amiable bartenders mix up big, bold and icy-cold. The martinis here are such a hit that the Avenue Grill even has a martini club, but you don't need to join in order to feel welcome at this bar. Although $5 martinis are a specialty during happy hour, which runs from 4:30 to 6:30 p.m. weekdays, the bartenders keep mixing them all night. An evening at the Avenue will leave you shaken, if not stirred.
