Red Mango cannot compete. Cocomero has a great selection of yogurt flavors with varying fat content and an amazing toppings bar.
I love that it's self-serve. I almost always want to fill the cup because it's so delicious, but it's nice to have the option of getting less.
I tend to either get all fruity flavors (mango, peach) topped with yogurt chips and blueberries (which are big and plump), or get richer flavors (red velvet, cheesecake) topped with yogurt chips and cheesecake bites. They rotate their specialty flavors, which is sometimes sad if one on rotation is your favorite - last week they had taro, which is a root vegetable popular in Hawaiian cuisine. I'd had it fried like potato chips before, but it was AMAZING as fro-yo!
