IMO, the best place for inexpensive, local eats is Yvettes. You can get a nice plate for $10 (they may have raised prices since I was last there) that includes some meat and 3-4 side dishes--johnny cakes, fries, salad, etc. Ok, we eat the $15 plates, and I load up on apps and Ti Punches ala Gabriel, but we have no control.

Also try Le Taitu as their French lunch selections can't be beat for some $14. Salad, Plate, and drink for that price.

Ital's on Bush road should not be missed. Vegetarian meals, no alcohol, but wonderfully flavored farm to table eats. Makes me happy after the excesses of normal island cuisine.

None of these are beach front but great tasting, local cuisine, and very inexpensive.
