We went to Boma last February for the first time and the experience was less than stellar.
The line for the meats was absurdly long and when I timed my wait, it was 20 minutes. When you have three kids less than 5 and two adults taking turns to go through the food line, it makes for an awful long wait before the whole family could all sit together.
I have heard great raves about the food on this forum, but the food was really no different than any other buffet, Disney or otherwise. Fish, meat, standard salads, and soups. Not worth $50.
