I have been to Tea Space way too many times now. I think it's great that they've added food items to their menu, but I have yet to try any. I still say their best drink is the ice milk drink (which they've given cute new names to them that I don't remember); it is also the only place that even offers this kind of boba drink that I've found in Vegas. Their boba is warm, chewy, and perfectly sweet.
The only tricksy thing about them is that a "Teaspace small size" is typically everyone else's regular; and a "Teaspace regular size" is typically everyone else's large.
Also, i do appreciate that they always offer you a menu, even though I already know what I want 99% of the time.
