I've never quite understood the Pinkberry concept--frozen yogurt with fruit on top equals wait in line for fifteen minutes and spend most of a ten spot? Plus, it's not something that you can easily patent. I mean it's frozen yogurt with fruit on it. So, it shouldn't be a surprise that hundreds of frozen yogurt shops have sprung up all over LA. On about two blocks of Brand Boulevard in Glendale there are three such shops. Dolci Mango, however, has added something to the concept that really appeals to me: pay by weight. It's self-serve, take as much or as little as you want, then add fruit and toppings yourself. Some days I get away for under two bucks. The idea must be working--this store used to be a standard yogurt shop but changed over to self serve soon after its sister store in Montrose made the move. On Friday nights in Montrose the lines can outdo Pinkberry. Still, I don't mind standing in line for frozen yogurt with fruit on it when I can walk away with the better part of a five dollar bill still in my hand.
