Sure, plenty of places serve fashionable, frou-frou martinis, featuring chocolate or pineapple or organic juniper berries. And the affable bartenders at the Avenue Grill are willing to make a martini just about any way a customer asks for it. Over the years, this go-to spot has made other changes, too, including recently adding a Saturday brunch. But when we're ordering a martini, we like to cling to tradition, and our favorite remains the classic that they've been pouring for more than two decades: big, icy and guaranteed to leave you shaken, if not stirred.
