Re: Provo, Turks and Caicos, restaurants costs and recommendations

We are heading to Turks and Caicos next week, staying in Provo and with a rental car.
We prefer local "interesting" food rather than places like hotel restaurants. Wondering if you can give a sense of what we should expect for costs (not including alcohol but including tax) for a meal for lunch? for dinner?

Also, we will be there during the birthday of the 20-something in our group. Looking for a 'fun' place for dinner -- but for someone who does NOT drink, so perhaps a broader definition of 'fun' than a wild and crazy drinking crowd.

Of course, your 'must eat at' recommendations are always welcome!
thanks!
