Have been in Hokkaido since 1998, and lived in Sapporo for 7 years. Susukino is the part of Sapporo south of the Odori Park downtown area where lots of bars can be found. The city has almost 2 million people, so it has plenty of restaurants virtually everywhere, though. It's an easy city to get around, but I have never really found it to be all that exciting from a tourist point of view. Go 45 minutes away to Otaru and you can see a canal with Russian warehouses on the side, a steam-powered grandfather clock on the sidewalk, glass blowing, and shops with glass or wood crafts or music boxes, as well as a whole street with sushi restaurants. Sapporo has its Sapporo Beer Factory, which is nice for a tour and a meal of genghis khan (roasted lamb). About the only other thing of culture is the Hokkaido Shrine, but considering you'll be in other cities, it might be a let down. Google it. Also check out locations for Ainu displays. South of Odori Park is the covered shopping arcade (12 blocks long) called Tanuki Koji.
