Being a big fan of ice cream, I'm very much loving the surge in fancy ice cream places in Toronto. I make an effort to try out everywhere I hear of :)
Bang Bang has one huge advantage: ice cream sandwiches. The cookies themselves are delicious, as is the ice cream. They have all sorts of interesting flavours like London Fog and seasonal specials like Ontario strawberry. I've got to say it's won me over for the simple flavours.
The less fun part is the line. Bang Bang is really popular. Every time I've been it's been around a 20-30 minute wait.
