Taxis are great, but very expensive especially if going from one end of the island to the other (fixed rate/schedule which you can find online).

Some good restaurant choices in the East End are Falcon's Nest (casual seafood), Artisan (pizza) Ben's Pit Stop and Le Bon Pain (bakery/breakfast), Also there are 5-6 beach bars with food on Shoal Bay East (daytime only, for the most part) - Elodia's, Uncle Ernie's Madeariman, Hank's, Tropical Sunset, Gwen's).

No shortage of great restaurants on the West End - - much wider selection, just need to know what you are looking for.
