You'll sit with just your family, like any regular restaurant.
When you first sit down, they'll bring you some plates and a huge lazy susan (rotating) platter that has bowls of yummy chicken wings, salad, green beans, shrimp & vegetable wontons, and fried rice. That's your appetizer platter. They'll bring you refills of any of those items for as long as you like (I think we had 3 or 4 bowls of the chicken wings)
Then they'll start bringing over these huge skewers ( like 4 ft long) of various meats - turkey, beef steak, roasted pork, and grilled shrimp that you'll see them roasting over an open flame when you walk into the restaurant. The server takes as much meat as you want off the skewer and puts it on your plate, then moves on to the next person. They keep bringing them and bringing them till you're bursting at the seams.
You can also have desserts and fancy tropical drinks if you like, but those are extra cost. You can see them here:

All the while this is going on, there's singing, games for the kids (hula hoop contests, sweep the coconut races, etc).
This is absolutely our favorite place in all of Disney World to eat. You'll love it!
