It's Tokyo Tokyo's latest chicken creation. It's a BIG piece of chicken fillet, [allegedly] coated with panko, then fried to a golden crisp. It comes in three variants: Original, Teriyaki, and Asian Spice. We asked the cashier about these and she said that the Original is just like ordinary, breaded fried chicken, the Teriyaki is fried chicken smothered with the restaurant's delicious sauce, and the Asian Spice is fried chicken with a special rub. We deemed the first two familiar, so we went for the Asian Spice.
The chicken was moist, juicy, and not too oily. The rub though was too salty and sharp. And the barbecue dip that came with it didn't temper the strong flavor of the chicken for it was also sharp, too tangy. We needed a lot of rice just to mute some of the sharpness.
The Teriyaki variant might have been the better choice.
An order of the Big Chicken Katsu costs Php 169.
