Some of the restaurants in the BW area don't do lunch. You might consider an Ale&Compass at the Yacht Club. Beaches and Cream does lunch, but the could be an extremely difficult reservation to get for 8 people - it's pretty small inside. Maybe grab something at the BW Deli and dine outside by the water..... You can also mobile order at either MarketPlace (one located at YC and one at BC) - good food, not fancy.
