There is no "best dish ever" for me.
Some of my favorites of all time are King Crab Legs at Bob Chinns, Kona Crab at Bob Chinns, Pollo di Anna at this little itialian place called Giacomos, Lobster Claws, Egg Curry, Tandori Chicken, Penang Curry with Chicken, Filet Mignon from several different restaurants, Tiramisu at Giacomos, Baked Alaska, Cherries Jubilee, Porterhouse Steaks Cooked on my grill, Kung Pao chicken & Shrimp Combo from a little family owned take out place called "Wa Feng Chop Suey", Mongolian Beef from a slightly larger Chineese Restaurant called "Yen Yen", Pork Tenderloin the way my Mom cooks it (as well as my grandmother, and when I was really little, before she passed, my Great Grandmother prepared it that way too).
My favorite "huge fricken feast" is probably turkey cooked on the grill smothered with bacon and spices with gravy, served with Mashed potatoes, Stuffing, corn on the cob, sweet potatoes, buttermilk biscuits , salad, shrimp cocktails, garlic bread, asparagus, carrots, and of course, a nice cold GOOD Beer, (Hoegaarden, Guinness, Stella Artois, Sam Adams, Linies Red, Killians Red, etc)
EDIT: I have decided that I like food TOO much, heh
