A good place for an informal gathering. Denny's is a pretty standard place here in Japan. Do not expect your free coffee refills or large breakfasts, since in the Japanese culture breakfast has a different approach. The service is good enough taking into account they have a rather limited personnel, but from time to time you will find yourself waiting for more than 10 minutes just to get served. The mood is ok, but the lack of a physical division between the smoking and non smoking areas made it barely a joke if you dislike the tobacco aroma.
