Opa! Oyster hours come to Doretta. Monday through Friday, you can settle in at the bar for $1 bivalve varieties. Three different shellfish options will be on offer from 4:00 to 6:00pm and again from 9:00pm to closing time. Cucumber mignonette accompanies the bargain shucks, served chilled and raw. Make your way to Park Plaza to order up on the treats—questions can be directed to 617.422.0008.
