I will be visiting Tokyo next week on my own, and staying near the Kayabacho subway stop. I'd appreciate some recommendations of places that I shouldn't miss. Any type of Japanese cuisine would be great. I'm an adventerous traveller (and eater), but speak no Japanese. I'm certainly willing to do a lot of pointing, but it would be helpful to know if there are places that might be more managable for someone who doesn't speak the language. Thanks.
