If you are into Brazilian-style grilled meats, try Churrascaria Plataforma on West 49th Street, between 8th and 9th Avenues.
All-you-can eat (reasonable) prix fixe. They constantly circulate among the tables with sizzling skewers of everything from flank steak and prime rib to bacon-wrapped filet mignon and top sirloin, through lamb and bacon-wrapped turkey and sausages, pork loin and spareribs and …burp, excuse me. Yumm to bursting.
If you need a break from the carniverous carnivale, temporarily flip over your marker from green to red while you enjoy a very imaginative ultra-fresh salad buffet (white asparagus and heart of palm through tomato w/mozzarella and unsual pasta salads).
Only weak point is desserts (which cost extra anyway, so best skipped).
I was just there for the first time last weekend (Saturday, August 14), and truly loved it. (Also enjoyed the musical "Hairspray" while we weee in NYC for the day).
