Brent's Restaurant & Delicatessen   Jewish-style deli fare is hard to come by in the Islands, but Brent's, founded by Brent Brody of Brent's Los Angeles fame, offers the real deal, including deli sandwiches piled as high as the Empire State Building, chopped liver, lox and bagels, potato latkes, smoked fish, Dr. Brown's Cel Ray sodas, potato salad and really sour pickles. Their breakfasts, served all day, are favored by regulars, including such dishes as eggs Benedict, various omelets, waffles and such. Service can be slow because they're always busy.
