This hole-in-the-wall eatery in a residential district may be stuck in the 1990s, but its delicious Sichuan home cooking transcends time. It prides itself on eel dishes – wild onion eel is a seasonal delicacy; Tongfu eel is spicy and aromatic, whereas red-braised eel imparts a mild zing. You can expect heirloom recipes rarely found elsewhere like pork liver curd soup with bamboo fungus and potsticker duck squares, but which must be pre-ordered.
