Sapporo is quite a fun city to spend time in. I would recommend the Susukino district for its many karaoke clubs, vibrant nightlife, incredibly diverse restaurant scene, and some amazing coffee shops. Excelsior coffee makes an incredible cappuccino, and you can legitimately while your time away, watching people as you sample their coffee and pastries.
Speaking of people-watching, I was taken aback by the sheer funkiness of some of the outfits I saw on the streets of Sapporo and Tokyo. They love to accessorize, will experiment like crazy and wear it with complete nonchalance. The final result is quite delightful, like a Tim Burton film on steriods in Greenwich Village. I hope that makes sense to you, gentle readers!
While on Sapporo, I must not forget to mention Ramen Yokocho, or Ramen Alley. This is a narrow alley in Susukino that is crammed with tiny dives featuring some of the best ramen you've ever tasted. The price is just right, the menu is not complicated, and the taste transports you to heaven. I can’t think of a better way to spend 800 yen on a meal. And if you've eaten too much, there are some of the best karaoke clubs in all of Hokkaido around you to burn some excess energy off!!
