Tierenteyn-Verlent Mustard Shop ★ 4.7
Tierenteyn-Verlent has been making mustard at Groentenmarkt 3 since 1790: the barrel-drawn Ghent mustard is the city's most iconic culinary product.
Tip: Bring your own jar to have it filled from the original barrel; the shop charges less for refills than for new pots.
