I served this alongside a seafood chowder and an artichoke salad. The citrus flavors in the drink paired well with both of those courses.
1 1/2 oz. vodka
1 1/2 oz. Grand Marnier
1/2 oz. dry vermouth
dash of orange bitters
Add all ingredients to a cocktail shaker filled with ice. Shake well and strain into a martini glass.
