What to eat and drink in Mexico: dishes, etiquette and dietary tips

Mexican cooking is built on corn (masa), beans, chillies and slow-cooked sauces, and it is on UNESCO's intangible heritage list. The country is too varied for one menu: what you eat in Mexico City is not what you eat in Oaxaca or Mérida.

Mexico City and the centre run on street food: tacos al pastor carved off a spit with pineapple, tlacoyos and quesadillas filled with beans, cheese, squash blossom or mushrooms, pozole at night and tamales at breakfast. Puebla adds chiles en nogada, a stuffed poblano in walnut cream, sold mainly August to September.

Oaxaca is the sauce capital: seven moles, with mole negro over chicken or turkey, plus tlayudas (large crisp tortillas with bean paste, quesillo and meat), chapulines and mezcal. The Yucatán leans Maya, Caribbean and Lebanese: cochinita pibil slow-cooked in achiote and sour orange, panuchos, and sopa de lima with chicken and local lime. On the Pacific and in the north, expect seafood and beef: aguachile in Sinaloa, fish tacos in Baja, carne asada with flour tortillas.

Tap water is not for drinking in most of Mexico; hotels, restaurants and shops sell bottled or filtered water, and many cafés refill your bottle. Ice in busy restaurants and chains is usually made from treated water; at small stalls it is a judgement call.

Agua fresca — fruit, rice (horchata) or hibiscus (jamaica) in water — is the everyday drink and cheap. Coffee is often pot-brewed and light; café de olla comes with cinnamon and piloncillo sugar. For alcohol, beer is everywhere and cheap, mezcal is the Oaxaca speciality (sip, do not shoot), and tequila is from Jalisco around Guadalajara. Michelada, beer with lime, salt and chilli, is the standard hot-day drink.

Street stalls are the cheapest way to eat well: tacos, tamales and tortas usually run a few dollars. Sit-down places at lunchtime offer a menú del día — soup, a main and a drink for one price — which is the best value of the day. Tourist-zone restaurants in Cancún or on the Mexico City reforma strip cost several times a stall.

Ordering is simple. Point at what you want, say 'para llevar' to take away or 'para aquí' to eat in. Salsa and lime come free; ask for 'sin picante' if you want no chilli, though the salsa is usually already on the table. The bill is not brought until you ask: 'la cuenta, por favor'. Tipping 10–15% is normal at sit-down places.

Street food is the point of eating in Mexico, and busy stalls with high turnover are the safest bet: food cooked in front of you and served hot. Look for a queue of locals, a clean griddle and a cook who handles money separately. Avoid trays of pre-cooked food sitting out in the afternoon heat, and be cautious with raw seafood such as aguachile if you have a sensitive stomach.

Salsa can be much hotter than it looks — try a drop first. Fruit you peel yourself is low risk; cut fruit from a cart is usually fine but depends on the water used. If you do get an upset stomach, rehydration salts from any pharmacy are the first response; see a doctor for blood, high fever or symptoms past three days.

Vegetarian eating is easy in Mexico City and Oaxaca but not automatic: lard and chicken stock hide in beans, rice and soups. Ask 'sin carne, ¿con manteca?' and 'sin caldo de pollo'. Quesadillas, tlacoyos and churros con chocolate are reliable meat-free picks.

Corn tortillas are gluten-free, but flour tortillas, breads and some sauces are not — ask for 'tortillas de maíz'. Halal options are limited outside Mexico City; seafood is the usual fallback, and Lebanese-Mexican restaurants in Mérida and Puebla are worth knowing. For nut or shellfish allergies, carry a card in Spanish naming the ingredient, since shared oil and griddles make cross-contact likely.

Lunch (comida) is the big meal, roughly 14:00–16:00; dinner is lighter and later. The bill is never brought until you ask for it. Tipping 10–15% at sit-down restaurants is standard, and small change at stalls is appreciated but not required.

Sharing is normal: plates go in the middle, and tacos are eaten with your hands. If you are invited to someone's home, bringing a dessert or a bottle is a friendly gesture. For more on greetings, dress and daily manners, see the etiquette page.
