This post is to highly recommend Sea Salt (in Avalon / Stone Harbor). My husband and I ate there twice this past week (we enjoyed it so much that we went back). We eat out frequently and these were 2 of the best meals that we have had in the past year! The ingredients are all local farm fresh and you can really taste the difference. The chef is an artist at blending flavors and textures. An example is a wild boar dish that we ate twice. It had a sauce made from home-made sausage and blueberries. I would have thought that would taste weird but it was sensational! Other wonderful dishes were a fisherman's stew (with almost no liquid - spicy fish and sausage - yummy!), grilled endive with ham and toasted gruyere cheese.
The place is physically very small (just about 10 tables), and does not advertise. They have a website but it does not have much info there. I highly recommend it for an extraordinary meal.
I think they are open every night except Tuesdays through October (I am not sure what nights they are open after October). Prices were $30-$35 for main dishes (called "thirds") and $15-$25 for "firsts" and "seconds" (these are appetizers, soups, and salads - all large portions). There is also a $58 price fix "tastings" with smaller portions of one first, one second, and one third. It's a BYO.
