The chocolate manufacturer, known for its hand-crafted bonbons and gelato, plans to open in a space across from the outlet mall's food pavilion.
Chocolaterie Stam will open its third metro location in November at Altoona's Outlets of Des Moines.
Chocolaterie Stam's menu includes more than 50 flavors of gelato and sorbetto, its own coffee blend and several flavors and shapes of bonbons, truffles and other chocolate confections.
Chocolaterie Stam has two other metro stores — 2814 Ingersoll Ave. in Des Moines and Valley West Mall in West Des Moines — and several other locations throughout the U.S.
The outlet mall, located at 801 Bass Pro Drive in Altoona, is part of the Shoppes at Prairie Crossing, a retail, commercial and residential development south of Bass Pro Shops.
