The Sports Club/LA has staked its claim as the city’s most exclusive urban country club. Members have full use of the seemingly countless treadmills, free weights, basketball and squash courts, and swimming pool, not to mention spinning, yoga, and Pilates classes. But it hardly ends there. This club also features dry-cleaning services, babysitting, a full-service salon and spa, and a gourmet restaurant, blu, that serves up a special low-fat, health-conscious menu. And while it may be uncomfortable to break a sweat with so many beautiful people lurking around, that’s not a bad thing: The club is one of the best places in town for singles to mingle.
