If you need a little Western Style cooking while in Japan then Denny's is a perfectly good place to get it. Big menu, reasonable prices and the food is fine. We had breakfast there. Two breakfasts, bottomless filter coffee came to 600¥ each (£3.45 $5.88). Not huge meals (portions are always smaller in Japan) but fine. Service is good with a bell to call the waitress at each table and the decor is clean - if a bit dated. So to summarise. Reasonable food at good prices. Service is good and the restaurant was clean. Not bad for 600¥!
