Came here on a Saturday night with a friend and the boyfriend and it was definitely worth the 40 minute wait we stood in line for. Bang Bang is this cute little shop next to another quirky and super cute little shop called Crywolf (the folks there must have mixed feelings about people standing in line constantly outside their shop) and the lineup is constant. We of course went during the "rush hour of ice cream getting" (after dinner), on a weekend, on a hot day - so there were 3 cards against us.
We were all much too full to get any eggies or cookie sandwiches but we did end up getting a cone - single scoop. We had the earl grey, the roasted marshmallow, and the malt-teaser. The roasted marshmallow was a bit too sweet for comfort as was the malt-teaser but I really enjoy the latter b/c of the chocolately chunkiness. The earl grey was by far the best with an awesome lightness to it but strong in the tea flavour.
Overall, I would definitely go to Bang Bang's again and I really would love to try the other varieties of flavours they have...and definitely give their egg waffles a try one time.
