Things to do:
St. Louis Zoo (world class and it's free)

Science museum(also free) These three are all in Forest Park. If you come in the summer there is also the Muny Opera which is the largest outdoor theater in the US. Mostly musicals. There is also the St. Louis Wheel and the St. Louis Aquarium at Union Station downtown.
If you like to Gamble, there is Lumiere downtown and Casino Queen right across the river. Hollywood in Maryland Heights and Ameristar about 2 miles from there in St. Charles.
Missouri Boatanical Gardens (also known as Shaw's Garden)
