The best thing about TSUM is the large branch of the Tatar supermarket Bakhtele, which sells homemade Tatar food. Reportedly the food at Bakhtele is so good that many Tatar women have actually stopped cooking traditional pies, stews, pelmeni and the like altogether because even they can't compete with the perfection of local dishes that this supermarket has achieved.
