I've been to Twirl twice since moving to the neighborhood and loved it both times.
The yogurt and toppings are great. Caramel macchiato is especially unique and delicious. There was a fun guy working when the bf and I stopped by to grab to-go orders, who gave us sample "fish eggs"- these cool little pineapple bubbles that are filled with liquid. Hard to explain, just look for the little orange balls.
It definitely has a hipster vibe but I like that unlike most fro-yo places, it's a place where you feel comfortable hanging out for a while with friends. Not that fluorescent light-plastic chair atmosphere at most fro-yo places.
I will definitely be getting Twirl cravings so it's a good thing this place is so close to my house.
