Twenty-four-year-old owner Tommy from Milan is an easy-going restaurateur who declares only one rule inside his cozy, intimate dining room: “It’s a no prosecco zone.” This “red line” is drawn to showcase Franciacorta, a smooth, subtle Italian sparkling wine made via small batches (unlike mass-produced prosecco). This sets the stage for Da Tommy Osteria’s 60-seat getaway, offering high-end cuisine at bargain prices (no entree tops $29). The 10-person elbow-shaped bar, white brick walls, and random shelves of wine complete the owner’s authentic vision. An osteria is a woodier, more rustic trattoria where the root word is host, as in, you’re being hosted in someone’s home. Seventy-percent of the menu is vegetarian, which is a hit with the local Kosher crowd. Start with the Zucchini Cake and Parmesan Truffle Fondue or Grilled Octopus and Lemon Ricotta (a meaty white ‘sea sausage’ via Portugal). A celebrity chef designed the menu, taking it up a notch with fresh-made colorful pasta specialties led by scene-stealer Tonnarelli Cacio E Pepe (Roman Style Pasta, Pecornio, Black Pepper, $12!). The outstanding Branzino Al Forno (Pan Roasted Sea Bass, Capers, Olives, Vegetables) is served in a sturdy frying pan. This affordable feasting ground prides itself on only serving fine Italian wine and beer; the recommended Franciacorta is Contadiscastaldi Brut. Ps, the staff is Italian, so there will be no rushing here. Da Tommy Osteria, 14 Bedford St., Manhattan, New York, NY. 212-675-9080.
