Chef-driven burger joint Bunz Handcrafted Burgers quietly expanded its San Antonio footprint with a second location earlier this week, this one dubbed Bunz Express. The company marked the occasion with a social media announcement featuring local influencer Chris Flores, also known as eatmigos. The new shop, located at 6819 N. Loop 1604 W., officially opened Monday, April 24, according to a collaborative Instagram post in which Flores samples several burgers, chicken sandwiches and milkshakes made from scratch at the La Cantera-area shop.
