I usually get the 1/2 ice cream sandwich cookie which I find to be the perfect portion size. I actually like their cookies more than their ice cream selection. They have a variety of rotating ice cream flavours like the popular Totaro but I usually go for the London Fog with the oatmeal cookie. I have tried others but the flavours were not quite intense enough. They also have a warm chocolate chip cookie that goes really well with most of their flavours like burnt toffee and soybean walnut. They also have an HK egg waffle and ice cream combo which I have never tried and feel is way overpriced, and I think I prefer egg waffles on their own.
Expect average wait time of 15-25 mins depending on time of day and whether it is a hot day or not.
I find its sister shop Bakerbots a nicer location although they have a smaller selection.
