Houston Area question

My in laws are coming to visit in a few days. We just moved to Texas this spring and live about 45-60 min from Houston, so we aren't familiar with anything further in than about Roseburg/Richmond. We are planning on going to the Houston Zoo one day while we're here and I was wondering about places to eat in that general area. Nothing too fancy (aka expensive), just somewhere nice for dinner. Thanks!
