I really like all the Green Grotto bubble tea locations. They all provide you free popcorn once you sit down to munch on while you wait for the rest of your food/drinks. They have plenty of Asian magazines to read if that's your type of thing.
My favourite thing is that they have mixed size tapioca for all their drinks. Some people I know don't like this, but I love it! I have their points card too, but I don't exactly remember how the points system works.
During peak times, this gets really packed and since people go there to hang out, there's not a lot of turnover of tables. I've been forced to get takeout a few times because there were no seats available.
