One Day in Tainan: A Self-Guided Food Tour - Eater
"The owners of this stall-turned-storefront do just one thing, and they have it down pat. Marinated nuggets of Spanish mackerel are breaded and deep fried, then left to drain. Customers can pick between having it with a tangle of mian (wheat noodles), mǐ fen (rice-flour vermicelli), or just the fish in soup. Only after an order has been placed is the soup — thickened with cornstarch and flavored with a squirt of black vinegar — poured over the fish, which arrives at the table perfectly plump and flaky. Open: 6 a.m. to 2:30 p.m. daily. Price: from $60 TWD ($2 USD)
Directions: From here, make your way to Hai’an Road. Walk north to Minsheng Road, then east to one of the street-food epicenters of Tainan at stop 6." - Steven Crook
