Downtown Half Moon Bay isn’t a place you shop with a list. The stores along Main Street are independent, most run by the people who own them, and the shelves show it: books, home goods, clothing, work from local makers, art and jewelry, gear for the beach a few blocks away. Prices run the range, so you might leave with a paperback or with something you’ll keep for years. Give it some time. Half the point is the walk between shops, and there’s always a coffee and a place to sit when you need one.
