The Malt Shop 1751 Smizer Station Rd, Fenton, MO63026 The Malt Shop is "old school" in the best sense of the description. It has graced Fenton with its simple approach…More to business since 1972. You'll find window service and maybe a line as people eagerly wait for a freshly made malt or sundae -- or maybe a chili cheese hot dog and French fries. It features a traditional drive-in menu, a real flashback to the 1950s and 1960s. The Malt Shop stays open later during the summer and is closed from Thanksgiving to March 1.
