We ate out EVERY meal in Bimini and drank at most of them
Figure $25 for breakfast, $50 for lunch, $60-100 for dinner. It all depends on what you eat. We had a large fresh made pizza for $25 (serving 4 adults), cheeseburger for $13, sushi for $16, mahi-mahi for $28, spicy shrimp for $6, conch salad for $9, etc. those are all per plate prices (except the pizza). So it is "reasonable" considering you are on an island or at a marina. I pay that much for a cheeseburger at a marina here in TN!! So we were very pleased with the food and prices.
I think total with the room & slip at Bahia Mar for 2 nights, 5 nights & slip at The Sands, a hotel stop on the way home in GA, boat gas, souvenirs, golf cart rental, casino money, diesel for a 1,800 mile round trip, all food for the entire trip, all drinks for the entire trip, and having an AWESOME time in a BEAUTIFUL PLACE we spent about $3,500 per couple...... BEFORE the supplies we bought beforehand like gopro, memory cards, GPS app, radio, etc, etc
We would definitely go again too
