Well, the theming of Boma is really very minimal, especially compared to Jiko for instance. The servers, while good, have never been among my favorites (these kudos belong to FF) and the view??? If you're lucky you get to look at the pool walkway...So basically I'd say most of the Boma reviews are based on the food itself.
My take? While it's not the best food on property it certainly IS the best buffet and I hesitate to even classify Boma as a buffet (it's that good).
Certainly there are people who are not as enamoured with Boma as me, but generally the food tastes of these people tend to be quite pedestrian, IMO...If you're not afraid to step a little out of the box, Boma will satisfy...
