Dallas has filled gigantic voids lately in its quest to become a complete metropolis, from dependable mass transit that's not limited to buses, to biking trails that don't terminate on the front end of a bus. Filling the need for a genuine New York-style delicatessen, Zinsky's. A joint venture from the Blue Mesa and Pei Wei/Tin Star/Bengal Coast folks, Zinsky's is serving up an all-day, Jewish-deli-plus menu in a soothing, cafeteria-like storefront with light-wood tables and trim, red-tiled walls, and a slick monolithic wood-square ceiling armature to hide fluorescent lighting and ducting (they briefly considered leaving this exposed and calling the venture "Zinsky's Hip Urban Loft"). Many ingredients are either local (e.g., breads & bagels by Empire Bakery) or carefully chosen after a nation-wide search (pastrami/corned beef from Chi-town's Kelly Eisenberg; lox/whitefish from Brooklyn's Acme Smoked Fish); traditional classics include six schmears, all-beef dogs, meat-stuffed cabbage rolls, matzo ball soup, smoked salmon omelets, smoked fish platters like the "Three Wise Men" and, for those constantly asking the question "What am I?", chopped liver. Further stomach expansion comes courtesy of challah French toast, 1/2/3- story sandwiches (the brisket/pan gravy "Shor Thing"; the fried beef-bologna "Joni Bologna"; the three-bread, meat & cheese monster "The Zinsky", of which $2 goes to charity); and a week's worth of blue-plates like Wed's fried chicken tenders, Sat's prime rib, and Thu's "Mac & Cheese Festival", with four kinds of cheese, and on the main stage, a kind of crappy blues band. Because your need for a Reuben never sleeps, Zinsky's'll be open 'til at least midnight on Fridays and Saturdays: late-night feasting that'll ensure no matter what mode of transit you choose, you'll provide the mass.
