We have done both. We just got back home from our wedding stay at the world and stayed at AKL. We decided to do all the restaurants on property since they were all at our reach. I admit I was extremely nervous to do Boma for dinner because I had heard how a lot of things were sweet and/or spicy. I don't like spicy food and I absolutely HATE food that is suppose to be salty to be sweet. We knew we would enjoy breakfast because it has traditional offerings, but boy was I in for a surprise when we had it for dinner. IT WAS FANTASTIC!!!!! Yes, they do offer a lot of sauces and toppings, but you pretty much add it to what you want. The only thing that was covered in sauce were the ribs that were really spicy so I did not like them, but the flavor of the meat was good, just too hot for us. The food was delicious, the prime rib was to die for! The chicken divine. The breads, salads eveything was wonderful!!! I can't wait to go back!
Maya Grill is forgettable. Nothing special about it. To me it was not bad, but you don't want to go back because its plain. We had both breakfast and dinner at the Maya Grill and DH hated both

You will defintely remember your meal at BOMA!!! Go to Boma, you will be in for a treat! I do agree with a previous post, Boma is by far the best buffet at Disney World!
