About Us

Lock 4 is a family-owned restaurant at Smitty’s Marina in Belle Vernon, built around scratch-made food, welcoming hospitality, and a love for bringing people together.

Our name comes from the historic Lock and Dam 4 on the Monongahela River—a connection to the waterway we’re proud to call home. Whether you’re gathering for a family dinner, catching up with friends over cocktails, or discovering your next favorite meal, we want Lock 4 to be a place you return to often.

Come by car or boat, settle into our indoor dining rooms or riverfront deck, and make yourself at home.
