We've done breakfast and lunch at Tusker House. It is our # 1 character breakfast. The food is wonderful and there are tons of choices. The characters were fun, as well is the atmosphere. My girls loved the little parade they get to do there.
Lunch was delicious. I'm very picky and there was so much that I ate. The carved meats are some of the best I've had. There are lots of salads, sides, entree type dishes. The desserts are great (don't miss the chocolate chip cookies if you eat there.) This was in our top 5 of 18 meals we ate on our last trip!
Never done Boma, so I cannot comment on them.
