the Website is Costas Greek Restaurant - there is a complete menu with prices.
The phone number is (727)[masked]
Just confirmed Costas has on-site parking.
Parking can be kind of interesting in Tarpon so allow a few extra minutes & make sure you have a couple of bucks in cash. Carpooling may be useful.
There are a lot of places to see so you could do some shopping before &/or after dinner depending on your schedule. Two of my favorite places there are the Spice and Tea Exchange & The Spiceman's Kitchen - both are on Dodecanese Boulevard (the waterside street)
