I stopped by to have the much touted Vietnamese Coffee flavour. I found it to be quite similar to regular coffee flavoured frozen products, but a hair more bitter. The real bummer about it was the texture. It wasn't smooth or creamy. Instead it was kind of gritty? Not the most pleasant to be sure.
They do have lots of other flavours available, but if it's busy, you're limited on the amount that you can test before making your ultimate decision. For the price, I would rather go somewhere with a better textured treat.
