Ohio ? According to record keepers, the world’s biggest buffet happened in Las Vegas. The record may not stay there, though.

Restaurants, bakeries and family cooks in the Amish region of northeastern Ohio are uniting today to challenge the mark of 510 buffet dishes served last year at the Las Vegas Hilton.

Organizers plan three two-hour sittings for 1,000 people each at $11 apiece at the Amish Flea Market. Proceeds will help feed the needy.

The nearly 600 promised dishes include Hungarian sauerkraut soup, corn casserole, garlic mashed potatoes and sweet potato souffle.
