The hotel provides delightful daily buffets for about 3,000 yen (15 quid to you) and you get to munch through Japanese and European dishes (including an amazing seafood curry) along with a worryingly wide selection of desserts. Plan to stay 12-3pm for a real test of character. Do not then get smart and go on the nearby rollercoaster but head for the gorgeously sedate Koishikawa park nearby in a desperate attempt to shrug off the undeniable excessive indulgence. Also recommended is the buffet at the Hotel Edmundo for a slightly cheaper blowout.
Tokyo Dome is near to Korakuen metro station. The Edmundo is near Iidabashi metro station.
