Twist Frozen Yogurt Calabasas, Los Angeles

Like most self-service fro-yo shops, Twist Frozen Yogurt offers a variety of rotating flavors—generally 14 to 16—and a toppings bar with up to 70 choices, including cookies, nuts, and fresh slices of fruit. And like the other shops' yogurt, Twist's yogurt is kosher, is either fat-free or low-fat, and is full of healthy dose of live and active yogurt cultures.

But Twist entertains more than taste buds. Each location lets visitors play on provided iPads or browse free WiFi until closing time at midnight. And on certain special occasions, the yogurt shop transforms into a birthday-party venue complete with games and activities, such as a piñata full of frozen yogurt.
