Vegan in Zihua

The big supermarket, Commercial Mexicana, has anything you might want outside of fresh fruit and veg which are much better back behind the Central Mercado. It now has a complete half isle of Organic brands of most everything, and for those who need it a gluten free section and a diabetic section. It has tofu. It had this morning 5 brands of quinoa, six brands of sushi rice, every asian sauce and spice you could want, etc..
As was mentioned we have a wonderful Saturday market from 9 to 2 (NOT by Casa Arcadia for the last year but behind the museum by the school.) It has food to eat prepared by the Copperativa Eco-Vegana and includes raw vegan options along with music and art and wonderful handmade soaps and lotions and much more. I wish it had more organic produce.
There are probably no restaurants that have vegan options on their menu in Zihuatanejo, but if you google vegan travel cards there are many options to print, some free some not) that explain your dietary needs in many languages.
