Having worked on several optical systems there for over 25 years, I can say with confidence that the McDonald Observatory Visitor Center is a world-class, 5-star public astronomy facility. All the staff are great people, the Star Date Cafe serves delicious sandwiches, the displays are state of the art and changed often, the auditorium is super, and the grounds are immaculately kept. Check their online schedules, and if they have a public viewing night and you see clear skies, treat yourself to the best telescope viewing in the entire country. That is not an exaggeration.
