The Bon Restaurant has moved. It is now only a block and a half away from the bus drop-off near the Narita Train Station. After getting off the bus, turn RIGHT and go down the hill. Continue across the street and go one block (about 250 feet) and look for the the Spiral Staircase sign in the front of the building. The restaurant is on the second floor, is larger, and has more seating than the old location. It is still all you can eat with a beer under 2000 yen.
