I was at Thomson Plaza for lunch, so I ran some speed tests for you.
It would only be fair to note that in between the two tests I lost all signal, dropping to GPRS, then 3G, for about 10 minutes. That could have been the tower power cycling through. (Or "On-Off"-ing as locals like to say).
Also, in lots of places it is not that fast. This is one of the better spots.
And here are the details from one of the tests:
