Tyler Cowen has published a new edition of his guide (the 15th, dated Feb 2004). Unlike the last several, this one appears to actually be fairly thoroughly updated. The commentary at the top is basically re-written, and is even more curmudgeonly than before. The listings are more up-to-date; for example, the listing for Formosa Cafe (formerly part of the 17 "you must try" list) accurately relects the current situation of the place (hopefully soon to re-open in a new location) which AFAIK only became known in the last few weeks).
All in all, a very useful piece for us Chowhounds.
