Like the Japanese after-work taverns that inspired it, this raucous new spot in the Verb Hotel near Fenway Park prizes good drinking as much as good eating. The kitchen turns out marvelous sushi and sashimi, charcoal-grilled skewers, ramen and more; the cocktail list alternates goofy party drinks (frozen White Russian, anyone?) with serious craft concoctions. Working the latter idiom, Mr. Swisher deftly underscores a hoary classic with a surprising culinary element to subtle, dreamy effect.
