The excitement is growing as our trip to Tokyo gets closer. Because we will be in Tokyo for only about a week, we are trying to zero in on a good tonkatsu restaurant near (walking distance) of the subway routes. Also hoping to get comments from the Tokyo Chowhounds regarding "Moo Moo Paradise" restaurant which we have been told is a good all you can eat shabu shabu restaurant. Lastly, regarding sushi restaurants, what would be considered a good deal in terms of cost for nigiri sushi plates? (example, toro and hamachi ).
