Quan Chay 126 serves authentic vegan Vietnamese noodle soups focusing on Southern-style hotpots like lẩu vịt nấu chao. The venue is small and casual with mostly takeout service and a single outdoor table for dining, run by two local women without English menus or service. Prices are very affordable, with dishes typically around 35,000–300,000 VND, and the food includes fresh herbs, fried tofu skin, taro, and rich coconut flavors, creating a homely experience reminiscent of traditional home cooking.
