(psst, I plated that)
Lacroix's greatness resides in its ability to wow you with new foods and flavor combinations, without forgoing importance of taste, whereas a bistro like Parc aims to wow you in its recreation of the classics. Both can be great, but they are in different realms of greatness. I would call Chipotle an incredible restaurant, but could I compare it to a restaurant with a completely different aim and philosophy? Absolutely not. Maybe all restaurants shouldn't be rated 1-30 on food by Zagat. Most restaurants aim for great food, yet there are definite sub-categories determining how they go about doing so. Can Qdoba really get a 17 while Le-Bec Fin gets a 27 (actual 2009 Zagat rankings)? Is their food even somewhat comparable. Both are great in their own sense (at least I think so, big greasy burritos, and roast rack of lamb both hit the spot at different times).
