Since the weather here sucks for the better part of a year, tiki bars are something of a necessity. And there are few better ways to get through a grey, grimy Boston evening than by camping out at Shore Leave, which looks like a filming location for South Pacific. With an extensive menu of fruity cocktails, it’s more a bar than a restaurant, but the menu of small plates and shareable dishes is enough to get you through dinner. Stay for a while and order the scallion pancake with king crab dip and some Filipino BBQ ribs for the table.
