I think it also depends on how you eat. If it's just about food on the plate (Russian style), then that's easy. But if the dishes are supposed to be in pots and pans on the table and everyone can help themselves, like it used to be, then it gets tight. And if it's Asian (or raclette), then it's no longer possible. I think that for such rather special occasions you can also work with side tables and serving carts.
