I've been to berri a couple of times now, mainly for the super cheap, guilt-free $1 small froyo. I do have a feeling that this place isn't going to last very long unless it starts to differentiate itself. The past couple of times I was there, there're only 3 flavors. I didn't like the mango and the vanilla, so I always get the pomegranate. They need to add more flavors and make sure that each flavor is good. The one reason why I'm not a huge fan of cocomero is because I feel like there're too many flavors to choose from and no one flavor is amazing. Berri should take the Red Mango route and stick with a couple of solid flavors and market itself as a more premium alternative to the self-serve cocomero.
oh, and also, make green tea one of your flavors!
