Famed as a food shop, Xíguela runs a small adjoining café whose fresh salads, sandwiches and other light fare make this a delicious and healthy lunch stop. Hours are the same as the shop, so you can simultaneously eat and stock up on Xíguela's wide range of organic, home-style, and locally grown foods. Delights include fruit jams, oils and honeys; taro chips; grains; couscous; wild rice; amaranth flour, cookies and sweets; maguey syrup; homemade yogurt - the list is endless. Xíguela is a treasure-trove of enticing and often unique food products, many of them difficult or impossible to find elsewhere in the city.
