I know I was really really disappointed because Thuy's Cafe couldn't make any decent boba... Well my friend told me that a few buildings down in the same plaza at Halong Bay they made some pretty kick butt taro boba. I went over there before class one day and wooooieee it was good! It wasn't too sweet and it was blended nicely. I was a little hesitant because this is a dim sum/Chinese/Vietnamese restaurant, but man was it good. It was definitely taro and the boba wasn't too hard or soft. It was pretty nice, I wouldn't say it was perfect but it was good :).
