Being there on their grand opening night, I was able to stand in line and watch them make many dozens of shakes for a good hour before coming to mine. Now it was grand opening night, so by no means will I be reviewing them for the speed of service: their line was out the door! This review will be solely on the business & its product.
The store is really hip! Love the pink colors and beautiful chalk-like drawings on the walls. Those kept me occupied for a while..
Watching many dozens of shakes being created, I noticed a few things..
First off, each shake is totally customizable to your taste buds. Like strawberries? Oatmeal creme pie? Ho Hos or Fig Newtons? - They'll mix it in! But the amount of it that they'll blend into your shake is very very little -with a tiny splash of milk. Only a few M&Ms, half a Ding Dong for such a large shake. The rest of the shake is composed of frozen yogurt (or soft serve ice cream? Not too certain.)
I had a shake with Hershey's Cookies N' Cream mixed in, while my friend got the Morning After (maple syrup, bacon, & orange juice - it was weird!)
Sweetness on both was way too sweet for the both of us. I had to stop by a store before reaching home to grab some water. It's something that I'd only crave a few sips of and be done with.
They were also quite runny for a shake. I'd imagine them to be more firm.
Shakes are a bit pricey for me at $5-$7 a cup. They do have a very wonderful "buy one give one" thing where they donate a meal to Three Square with every shake! But I'd be happier donating to Three Square myself. But an extra star for their cause :-)
