SANTA MONICA. Thanks to more than 150 high-end shops, fashionable Montana Avenue is a veritable shopper’s dream. Small, privately owned boutiques and famous clothiers checker the tree-lined strip. Spend an afternoon perusing the likes of Three Bags Full, A.B.S. for Women, and Weathervane for Men. Afterwards, replenish your depleted energy over coffee and a pastry at one of the area’s many sidewalk cafés.
