TravelToo,
It sounds like you've (hopefully) let your 3 yr. old experience more than just cheese & mac & fries. If so, your choices of BOMA and O'Hana's probably boils down to a matter of exquisite tastes vs. very good food with entertainment. If your little one enjoys participating in games, you might want to try O'Hana's (Polynesian, not Japanese). However, if you want something very different, try BOMA. The atmosphere is just the beginning of what should be a wonderful experience. The chefs and servers are eager to explain any and all dishes. Most of the food, while seasoned, is definitely not too spicy for almost everyone. We found, on our first time, that having the chefs describe the ingredients and flavor, then tasting almost everything, then going back for more of our favs, was the most satisfying way. Now, when we go, we find all the new items and go through the same ritual. If you want a different experience, definitely go to BOMA. Did I mention the desserts? Quite a bit of variety, much more so than O'Hana's. One other thing. If you like noise and a little mayhem, go to O'Hana's, since BOMA is relatively quiet. If you want to relax after a long day at one of the parks, go to BOMA and enjoy! Then tour the grounds to walk off the little bit of food you've put away!
