I will be visiting Mex. City for several days, staying at an apt. near Bellas Artes. I would like to shop for culinary tools: comal and many other types of implements (not raw ingredients) used to prepare Mexican food. Also large serving platters, party ware,typical paper flags etc. Can any local cooks give me stores or mercados in centro historico (names and locations to give cab driver) or not too far from there. I will have to cab it as I hope to buy more than I can carry on the Metro.
