Not sure if you're already done with your test, but I'll still post what I've heard about this center.
It's near (or in) Electronic City, which means that you need to plan your timings properly on the test day. The express way may be a bit crowded in the morning due to obvious reasons. So plan properly.
The only other thing I've read (in another forum) is that the restroom is not near to the testing stations (In the MG Road center, it's like you come out of the testing station and two steps away it is ... ). Here, it takes about 2 mins to reach the restroom
I found the description of this particular aspect as a review of the center a bit funny, but since someone mentioned it earlier, so I'm just doing the same.
Nothing apart from these two pointers.
If you've already written the test, do give a review of the center and please point out if anything written here is amiss.
Best of luck!
