If you are not very adventurous eaters, this might not be the restaurant for you. You will find many dishes are spiced (not hot) and flavorful. However, you mentioned that you like Boma, which has very flavorful and highly seasoned dishes. At the same time, with black beans and rice, fried plantains, and many chicken and meat dishes, you may find something that you like. Without knowing your personal tastes, I would say that if you like seafood, that section of the menu would be less of a stretch out of your comfort zone, possibly. Hope you have a great meal.
As an aside, if you are looking for food close to the Cirque theater, you may enjoy the fare at the House of Blues.
