Here, the mien is friendly, reading the deep menu is like falling into a wormhole, and the portions are grand — and it all adds up to make this New York-style Jewish deli a worthy stop for breakfast, lunch, or a gargantuan cinnamon roll for the road. JJ's boils more than 20 kinds of bagels every morning. They're of the giant, fluffy variety, and they do best under a mountain of whitefish salad or lox. Hot sandwiches on rye with stacks of pastrami or corned beef are also top-notch. An underrated nook on the menu is the robust knish selection, which includes a glorious doughy knob perfumed with bacon. And if you're ever feeling under the weather, we suggest picking up a bowl of Jewish penicillin, a.k.a. a hearty, comforting bowl of JJ's matzah ball soup.
