Bistrot Du Coin shared by @eater says: ""This Dupont Circle institution has been making French-style mussels ever single which way for over 20 years. With over seven preparation of the their mussels, from the classic marinieres and provencale to a meaty prosciutto and French ham pot and a lobster bisque version, you’ll never get tired of the moules frites here. Half sizes are perfect for an appetizer, while full sizes come with fries."" on Postcard
