Sit-down, Le Cellier, hands down. It's my #2 overall at WDW - only the Brown Derby is better, IMHO.
Counter service it's Electric Umbrella all the way...it's usually not crowded at all during lunch because everyone has moved on to other sections of the park by that time. It's just typical park fast-food, but I have found the food and the toppings bar to be the freshest in the park (Again, overall WDW, it's #3 in my eyes, though - behind Pecos Bills and Cosmic Rays at MK).
N.E.D.
