We did Boma for breakfast and dinner and had a great experience with both.
Dinner at Boma is now on our ever-growing WDW "Must do" list, and we will be back with my BIL in November. I will agree about the noise and crowds (some folks just will not keep their kids from bothering other diners, and the buffet format encourages the kids to get up and roam, but we try to go with the flow).
DH and I LOVE to try new things, but nothing at Boma was what I would call too spicy or scary. The soups were sublime, DH loved the nut-crusted salmon, and I was crazy about the flank steak in wonderful spices. I love that the desserts are minis, so you can sample and enjoy everything.
We did make one mistake: We were novices with the ice cream cookie sandwiches at the Main Street Bakery and ordered one apiece (should have shared one) after lunch. Therefore, we were not starving by the time we got to Boma. Learn from our mistake and be hungry!!
Also, take our advice and arrive early for a drink at the Victoria Falls lounge. Great bartenders and a beautiful setting to enjoy a drink (without the little ones) before dinner.
I hope you enjoy!
