Boma is the only buffet I do! My son has loved it since he was 4, now 14. Boma has as a good amount "American" food along with itd African specialties. What I love is the freshness of the salad dressings, the fragrant soups and most of the African dishes, some sweet and some savory. We love cous-cous, hummus and boboti, but I also love a good piece (or 2) of rare roast beef.
If you aren't adventuresome at all, then it's probably best for you to focus on a more typical American buffet! It's too much money to end up being disspointed, that why Disney has different strokes for different folks!
