When I first started going to this place the ice cream was just decent but it wasn't very special. However, I visited QQ today after a few months and I was very pleasantly surprised. You only need 8 points for a free ice cream (it used to be like 10+) and you can pick 3 toppings now (before it was only 2).
I highly recommend the oreo ice cream (men N black) or the mango ice cream. As for toppings, I really recommend the mango boba, even if it doesn't seem like it would taste good with the ice cream flavour you ordered.
Also make sure you get the whipped cream and condensed milk as they don't count towards your 3 toppings.
