Tuna's is on Biscayne right on the marina so you can enjoy sitting outside on the water, enjoying a glass of wine and watching the sunset or the water. Their menu is extremely varied with all kinds of seafood and steak, soups, salads, wine, etc. They also serve desserts. The thing is, this restaurant lacks that certain something, that spark to make it really great. Maybe it's the name? Who knows, but with such a prime location I expected more from this place. You'll most likely leave full and satisfied but it's got great potential to be superb.
