Hello incognito,
Thank you for your question. As someone that enjoys eating out for breakfast, I have say that Japanese aren’t really into doing Western-style breakfast. I am also looking for places like you mention and will do some research on the subject and get back to you. In the meantime, this is my tried and true:
The Le Petit Mec (Red Mec) bakery has amazing bread and coffee but is not that close to Hotel Monterey, maybe 10 or 15 minutes by taxi. Their potato bread, warmed with plenty of butter and a café au lait just cannot be beat, in my mind.
