Crown Ace Ueno Ameyoko is an old Japanese curry shop under the elevated tracks near Ueno Station and the Ameyoko entrance. It serves katsu curry and plain curry, with toppings added and large portions ordered, and the curry contains a chunk of pork. Customers buy meal tickets from a vending machine at the entrance and sit at island-style seats. At 1:30 p.m. on a weekday, three people were waiting inside, and the tonkatsu is tough and smells.
