Very unlike teriyaki chicken found anywhere else, the chicken appear to have been deep fried before being coated by a sweet sticky sauce and further drizzled with mayonnaise.
Scoop big spoons into your mouth, chew and let the sweet savoury flavours mix.
The deep frying makes the chicken taste extra savoury and the ajitama eggs is a cherry on the icing.
Soup on the side is the same soup for their ramen.
Side note: very decent ramen as well. I recommend their Special Ramen.
