Suggestions for South Indian restaurants

Hi everyone! I've been on the lookout for South Indian restaurants in the Houston area. I go to Shri Balaji Bhavan and the Meenakshi Temple Canteen pretty often (and love both) and have also tried Udupi Café, Shiv Sagar, and Sangamam (which I also liked), but am always looking to branch out and try new places. Looking for spots with great dosas especially. Thanks!
