    "West Pearl is truly a neighborhood unto itself, with a variety of shops & cafes and easy access to trails. Start your day with some tea and scones at Spruce Confections, enjoy browsing various antique stores and Two Hand Paperie, then select a bottle of wine at West End Wine Shop. Lolita's is conveniently located across the street to pick up last minute groceries for dinner, or you can enjoy a slice at Nick and Willy's and have some confectionary treats at Piece, Love & Chocolate. Settlers' Park is just down the street, as well as the trail heads to Red Rocks & Sanitas, and the Boulder Bike Path. When you live here, everything that makes Boulder so wonderful is only steps away!"
