I like shimokitaza, its just a few minutes from Shinjuku on the Odakyu line or from Shibuya on the Keio Inokashira line.

Yes its sort of a combination of Harajuku and Shibuya but much cheaper. Lots of restaurant, affordable shops.

I have brought lots of my friends there, and I've got positive response so far.
Might give it a little time. If you are planning to go to Tokyo Dome, then do it and then go to Shimokitawa late in the afternoon.
