Joy Machine guys are pretty friendly and a good shop if you bike needs service. If you are in the area of them and the right day of the week, check out the Cambodian restaurant and Westside market on the same street. Good eatings there. And the brewery in the area (Great Lakes IIRC....), and can't forget the Rock and Rock Hall of Fame on the lake.

Also check out Euclid Ave. Many strange buildings in the University Circle area and its rather a pleasant place to hang out (my wife lives there).
