I went with two of my friends to a restaurant in Mongkok called Oh Yama Japanese Restaurant (大山日本料理). I got stir fried beef tenderloin, which is pictured, as well as one pork belly skewer and two minced chicken skewers. The minced chicken skewers came with an egg to be mixed with soy sauce, which you could then dip the skewer into. While it was the most expensive restaurant I've eaten at so far, I absolutely adored it. It was izakaya themed and the food was incredible. One of the staff members was also particularly kind, checking in to make sure we enjoyed our meals.
