The Green Onion on Colley in Norfolk has a wonderful Wednesday night special.  All you can eat mussels with a glass of wine for $17 (?)  The meal comes with fries and bread, I assume to help absorb the liquid combination of butter and garlic that the mussels float in. This meal is always a pleaser and real easy to minimie spending at an otherwise pricey restaraunt.
