Minute Maid Park
The Houston Astros play in this modern-but-retro baseball stadium, which has a retractable roof and a monster a/c system to defy Houston's frequently changing weather. Upper-deck seats on the first base side have great views of the downtown skyline—even when the roof is closed, due to a very cool retractable glass wall. The stadium incorporates Houston's 1911 Union Station (designed by Warren and Wetmore of New York's Grand Central Station fame), which houses the ball club offices, retail stores, and eateries. Heavy hitters can rent out Union Station's rooftop, which has views into the stadium from above.
