DH is a very picky eater. He does not like to try new foods. I can't even get him to try Chinese. He believes every meal should have meat and potatoes.
We ate at Boma twice on the last visit, once for breakfast and once for dinner. We're scheduled to go back to WDW in a couple weeks. He asked if we were going to that "African" restaurant again. I told him I'd made priority seatings. He told me good, because he liked it.
Granted he mainly at the prime rib and other meats (maybe pork loin or chicken something), a salad, potatoes, and a couple other non-threatening dishes, he was willing to try the new foods. He even drank the juice combination for breakfast. Wasn't orange juice, maybe mango and some other stuff.
Personally, I loved Boma and would eat there anytime. The dessert bar is incredible. Is there a way you can walk through and see the buffet before deciding? That might help you make a decision.
Hope that helped...
