Seaside draws heavily from Portland, which means the expectation of good coffee is baked in. Several independent coffee shops on and around Broadway have responded accordingly, serving espresso from Northwest roasters alongside the usual coastal town breakfast fare. The best spots are typically a block or two off the main commercial strip — the highway end of Broadway is where the national chains cluster.
A good coffee shop in Seaside in the off-season is one of the more pleasant experiences the Oregon coast offers: warm, uncrowded, with a view of gray sky and the smell of the ocean through the door. In summer the same places are packed by 9am on weekends, so arrive early or accept a wait. Most have outdoor seating for the days when the sun actually shows up.
