I also really enjoy spending time around the Kichijoji area. In Inokashira park we went to:
PEPACAFE FOREST
It is in the park at the end of the bridge where you can rent the swan paddle boats. It's open air and has really great food! Good Thai curry and lovely cold drinks.
Also in that area, if you are a knitter go to Avril. It is a world famous yarn shop, they sell yarns containing steel:
AVRIL Kichijoji Shop in Tokyo
We also had heard about and tracked down a burger joint in Shibuya called W.P.Goldburger. It was a nice casual place to end a long day eating a (really good) burger and washing it down with beer. I had the basic Whoopi Goldburger, J. had the Kevin Bacon. Map:
