Siblings Mary Nguyen Aregoni and Theresa Nguyen, whose family migrated to Thailand after the Vietnam war, got started selling banh mi in the French Market before introducing reimagined Vietnamese food at the West Loop’s Saigon Sisters. At the forthcoming Bang Chop Thai Kitchen they’ll try their hands at fast-casual Thai. The 25-seat BYOB spot within spitting distance of their flagship will feature a small menu of familiar Thai standards; Saigon Sisters cook Amy Gajewski will lead the kitchen. Postings on Facebook indicate R&D trips to San Francisco and New York, and recipe testing of dishes like som tam, pork larb, and the crispy rice dish nam khao tod. Bang Chop should be open by late September.
