If you care to line up, this may be some of the best ice cream in the city. I really only lined up for these flavours: Taro and Chestnut Matcha.
Went on a Saturday night around 8:30. Lined up for about 30 mins, and they ran out of HK Style Waffles (boo) so got an ice cream sandwich instead.
If you like Bang Bang but don't like waiting in line, I suggest you go to Bakerbots in the Ossington area instead. They serve the same ice cream sandwiches but with fewer ice cream options and no HK waffles.
