Something ubiquitous in one region can be awesomely novel in another, like Southern-style grits in the far North, or use of the word "ubiquitous" in the deep South. Giving Bethesda a tasty schlice of NYC: Uptown Deli.
Proudly bringing the DC area the Jewish deli it so badly needed, Uptown's 2000sqft of finger licking authenticity, lined with photos of famous delis and posters of the Yiddish dictionary, and run by a dude who "moved [his] way up into management" of bagel shops and was the son of kosher butcher, meaning his dad was anything but gentile. Loaded sammies include the hot steamed corned beef/creamy coleslaw/rye "Cloak and Dagger", the "The Big Fresser" (Yiddish for "glutton") with four meats (choose from everything from pastrami to chicken schnitzel) and three cheeses, and the tender beef/grilled onions/sharp provolone/horseradish/marble rye "Bris Kit", well worth the tip they'll expect you to drop. They've also got a slew of non-'wichable treats, like the "Belly Lox Platter" w/cream cheese/ capers/ muenster cheese/ bagel, the "Nish Nosh" (a deep fried potato stuffed with pastrami/deli mustard), and an egg omelet with nova salmon/eggs/ onion dubbed the "Uncle N.E.O.", also the name of the dude banned from babysitting you after mom found his stash of blue pills.
Sugary noshing comes via guilt-inducing goodies like halvah (sweet sesame seed candy), freshly baked Rugelach (pastry with sweet filling), and authentic New York style cheesecake, all of which their menu states is "A Gezunt dir in Pupik" or "Good Health to your belly button" -- so even if it's not novel, at least it's navel.
