Zack’s Frozen Yogurt

It’s only a matter of time before these ubiquitous frozen yogurt establishments (both the national chains and the locals) implode on one another as the fad goes its course. Maybe the strong will survive four years from now, but does anyone even get nostalgic for the days when TCBY was all over the place? Does it even matter to most people that they still exist?
I guess some are better than others, but I can’t help but feel that the real strength of this iteration of Fro-​Yo is the quality of the toppings, which often does involve fresh fruit or homemade cookies. The yogurt itself is nearly always forgettable – literally. I often can’t distinguish what I placed in the cup over the superior flavor of those toppings.
That said, Zack’s doesn’t really stand on its own at all. Flavors aren’t creative and (big minus) you don’t get to serve yourself or even add the toppings. Everything is done for you, and the counter is presented in such a way that it’s hard even to see the toppings available. (Zack’s provides a sign instead.) But I did catch a quick glimpse and I could tell that someone of those fruits were (gasp) prepared and (shock) probably even canned! At least the pineapple had that wedge shape that’s a dead giveaway. And half of the fruits on the sign weren’t even available.
It tasted alright, but with a billion competitors out there, what is going to keep this place around in six months – let alone four years?
