Michael Psilakis, of Greek descent, has long honored his heritage via Manhattan restaurants like Anthos, Kefi, Onera and Fishtag. MP Taverna might be his biggest hit so far, with branches in Roslyn and Irvington, NY,and most recently in Astoria, the bosom of the City's largest Greek-American settlement. The bi-level, corner space is modern and happening, with a busy bar where flat screens might be broadcasting soccer, baseball, tennis and football simultaneously. The giant, laminated menu is reminiscent of a Greek diner, but the food is elevated, from crab croquettes to grilled branzino to lamb shank. It's also no diner when it comes to the sophisticated wine, beer and Scotch list.
