Great fried clams.  Great haddock and clam chowders and lobster stew.  The place is packed most of the times so there's a wait for the food.  They encourage you to call ahead.  

What sucks is that it's only a couple of miles between Red's and the Sea Basket and I can't drive by either of them without at least a Red's Lobster Roll and a side of Sea Basket Fried Clams.
