Any thoughts about better restaurants that might be open in Mexico City on Christmas Day, or at least the week between Christmas and New Years Eve? I'm staying at a hotel in the Zona Rosa but would gladly cab it to a worthwhile spot. No preference in cuisine: upscale preferred. I've already called a couple places -- Izote in Polanco and Tezka in the Zona Rosa -- only to find both will be closed the week in question. Seems many restaurants choose that week for vacation, thus this posting/plea for help. Many thanks.
