Onigiri Planet (Taipei Songyan) is a small shop near Songyan Cultural and Creative Park that sells Okinawan-style rice balls, shrimp rice, and fried side dishes. The rice balls contain Spam and rolled omelette, with choices such as mayonnaise or mentaiko sauce, and honey mustard fries or mentaiko fries can be ordered alongside. Sets can take about 10 minutes after ordering, and the rice balls and fries are made on site, with takeout and delivery also available. Indoor seating is only about six seats, and the kitchen is attached to the dining area, so it smells of oil.
