Starbucks Coffee Company in downtown San Diego's Marina District occupies a ground-floor space inside The Headquarters at Seaport, the 1939 former San Diego Police Department building listed on the National Register of Historic Places at 789 West Harbor Drive. Original police-headquarters doors and window frames have been repurposed into the café's interior, blending WPA-era architecture with the chain's standard finishes — a preservation approach distinct from the new-build format at Village Cafe on the waterfront. Starbucks, the Seattle chain operating globally since 1971, serves its full espresso, cold-brew, and seasonal menu from this historic shell. The waterfront patio faces San Diego Bay near Seaport Village, positioning the location within walking distance of the USS Midway Museum and the Embarcadero pedestrian path. The breakfast pastry case — croissants, muffins, cake pops — serves tourists and convention-goers moving between the waterfront and Harbor Drive dining, pairing the chain's standard baked goods against the scratch-baked options at ASA Bakery in the downtown core. Convention Center overflow, Seaport Village foot traffic, and cruise-ship terminal visitors converge at this location during peak waterfront season, making it one of the highest-throughput Starbucks outposts in the 92101 ZIP code.
