We're thinking of grabbing some chow at Pujol in DF next week and wondering how nice we need to be dressed. We need to travel fairly light.
Ummm.....Pujol isn't exactly the kind of place you "grab some chow". This same question was asked not two weeks ago, here's the link to that thread - http://www.chowhound.com/topics/353216
You will most likely need a reservation for Pujol. You can book through Open Table if you aren't already in Mexico City. It's worth it, the room is sophisticated and chic as are the diners and the food.
Sorry, didn't mean to sound abrupt or dismissive, my own writing style has sometimes been referred to as "the disciplinary document from hell".
I think you'll like Pujol, everyone I've sent there has come back with only good things to say. The San Angel Inn is also a little on the dressy side, especially on a Saturday. It definitely wasn't a jeans and sandals kind of day when were were there. Think kakhi's and topsiders for the men and nice, detailed separates for the women.
Ultimately the days when the host made sure you were wearing a designer suit, shoes & watch before permitting entry are long gone.
Don't be a tourist (shorts etc.,)... but as long as you are comfortable in your own skin... Mexico City no longer seems like the type of place that denies entry based on strict dress codes.
