While the Kazan Church itself is a significant historical and religious landmark in Irkutsk, the area around the church offers a rich tapestry of Siberian culinary traditions. Irkutsk, often considered the heart of Siberia, is a melting pot of various cultures and their cuisines, including Russian, Buryat, and Evenki influences. The food in this region has been shaped by the harsh climatic conditions, leading to a focus on hearty, warming dishes that provide sustenance during cold months. Cuisine here traditionally revolves around locally sourced ingredients like fish from the Baikal lake, wild herbs, and root vegetables.
