I was in San Antonio about 5 months ago and was looking at all the pool rooms with my buddy. We heard "Banana Billiards has Diamonds", so we went there. We walked in, looked around, and walked out before we contracted hepatitis. I don't recommend that place. There is a small chance I just walked in when the wrong crowd was there, but I doubt it.
We settled on Fast Eddies. The tables were Olhausens, and they were clean and rolled straight. Did I mention the pool time was free? They had a great bar, hot waitresses, and great food. When I open a pool room, I will try to model Fast Eddies.
