Well, finding Taiwanese food in Rowland Heights is nothing unusual, though I don't recall seeing a new Taiwanese place open up in a little while. However Best Korner is worth noting for a couple of reasons. They have Taiwanese breakfast, Taiwanese lunch (bento box) and Taiwanese dinner items, and they have all of your Taiwanese favorites like stinky tofu, pig ear, oyster pancakes, pigs bloods, intestines, pork chop rice, not to mention the 30 item breakfast menu. Also they close at the tame hour of 9pm, probably to make up for their 7 am opening. Best Korner is located right outside the entrance to the 99 Ranch Market in Rowland Heights (where the sushi restaurant used to be), 1015 S. Nogales St., #130.
