Which Timmy Chan’s is the good one?

It just occurred to me that, despite having lived in the Houston area since I was a child, I've somehow never actually eaten at Timmy Chan's. I am extremely in the mood for cheap, questionably safe Chinese food. I've heard that they're actually in no way all the same franchise, and the ones that are just Timmy Chan's, the "original" Timmy Chan's on MLK, "TC Chicken and Seafood," "Timmy's Choice," etc are all completely different owners doing basically the same thing.

Which one is the best of the bunch? The canonical Timmy Chan's, if you will?
