Though touted to be their #1 cooked donburi, the Pork Cheek Rice Bowl was probably the least impressive among the three I've tried. The poached egg was slightly overcooked, hence we didn't get that runny yolk which would have tied the dish together. Flavour-wise, the marriage of ingredients was acceptable, but nothing really stood out for me. The tender porky cheeks were probably the only redeeming factor. I'd say, just go for the unagi rice bowl if you're looking for a lip-smacking intensely satisfying cooked donburi.
Koji is located at China Square, opposite the very popular Wang Dae Bak restaurant. The space is small, so do call for reservation is you are going with a big party.
