Stop at Robbie's Marina to feed the tarpon (it's a blast!) but DON'T eat at the Hungry Tarpon there. Horrible food and the service is even worse. We stopped in on the way into Marathon for lunch. 7 meals (10 people, of whom 4 were kids), and we were charged for 9 meals, then 8 when one was taken off since the chicken salad tasted like saw dust, and it was $82.00! They refused to do separate checks, the server made several rude remarks including "they're family and can you believe they're arguing about the bill" (we were actually trying to see how they could possibly come to the total) and the owner was a complete jerk! We ended up paying way too much and we have sworn to warn everyone we could about the place. Hopefully the money from feeding the tarpon has NOTHING to do with the owner of the restaurant. I wouldn't want to see him make any money.
