I'm going to be in the Big Apple in a week, and I was hoping someone could give me a lead on

1) A store that carries Onitsuka Tigers so I can try a pair and see how they compare to my Chuck Taylors,
2) A good LBS for fixie stuff; in particular I'd like to try the different sizes of MKS clips to see which fits me best.

Something in lower Manhattan would be easiest for me, but Brooklyn near the N-train would work too (I'll be stopping by L&B's before I leave). Thanks!
