Hmm...interesting.
The frozen yoghurt shops came and went here too, but these new shops have a bit of a twist - they are self service. You collect a one-size cup, and fill it yourself with as much 'soft serve' style yoghurt as you like. They have different 'base' flavours - french vanilla, cookie dough, chocolate, strawberry etc (usually about 8 at a time, and they change from week to week). You then move to the wall where you select from perhaps 25 different toppings - jellybeans, smashed heath bar, m&m's, gummy bears, etc. You can also add fresh fruit on top from the 'fruit bar' - blueberries, strawberries, kiwi, etc.
The cup is then taken to the register where it is weighed, and then cost is announced.
Cupcakes here are still on the upswing - I went yesterday and picked up 3 (sweet potato, red velvet, wedding cake) from the newest shop - but haven't tried them yet.
We haven't had the macaroon craze yet.
