Whats your general approach to an all you can eat buffet? Do you pile on the favourites? Or do you take a little bit of everything?

I've just been to one and I tried to have a bit of everything but I unwittingly filled myself up too fast by taking extra portions of things that I liked and didnt realise there was a whole bbq section I hadnt seen.

Next time I will do a round without taking anything first to survey every choice though generally I work my way through in the following order:

1) Food I've never had before
2) Food that is/looks expensive
3) Food I like

And as a second topic whats the best item you've ever had at a buffet?
