Bring your magnifying glass to the smallest tourist attraction in St. Louis. The Miniature Museum of Greater St. Louis is devoted to miniatures of all sizes, from small to itty-bitty to teeny-tiny. Visit the gift shop, take a class, or attend the twice-yearly Gateway Miniature Fair. The museum is open Wednesday through Sunday.
Visit the city's original bowling and martini lounge in The Loop. Pin-Up Bowl opens in the afternoon and closes at 3am. All ages are welcome with a responsible adult, until 9pm when the lounge becomes 21+ and the party starts. Walk-ins are welcome, but be sure to reserve a lane for larger parties because this bowling venue is popular among both tourists and residents of St. Louis.
