I would keep your reservation and try it yourself.
I am not a particularly adventurous eater, but we tried Boma for the first time on our most recent trip and we all enjoyed it. I am not sure that the type of food they serve there is at the top of my favorites list, but we all had a really nice time and tasted things we'd never had before.
I noticed that a lot of the flavors seemed to combine something spicy with something sweet. (Not spicy-hot like mexican food, but a spice flavor) They used cinnamon sometimes, coconut, chocolate, etc. in foods that I wouldn't normally expect those flavors in. It was interesting.
I only took one thing off the buffet that I "couldn't eat." (I didn't care for the watermelon rind salad). There were some things I went back for seconds, and some that I did not... but I'm a picky eater and I did fine at Boma!
