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

Irish cooking rests on grass-fed beef and lamb, dairy, potatoes, brown bread and seafood. The dishes below are what locals actually order, and where they are at their best.

Oysters are the one item with a real season: native flat oysters run September to April, and Galway and Clarinbridge are the places to eat them. Outside those months you will mostly see farmed rock oysters, which are fine but a different thing.

Pubs are the value option for a sit-down meal, and most serve food at lunch and early evening. City bistros and country-house kitchens cost more but are where modern Irish cooking is strongest.

Breakfast is often included with hotel and B&B rooms, which changes the daily budget more than any single dinner choice. Supermarkets and farmers' markets cover picnic lunches cheaply.

In most pubs you order food and drinks at the bar unless there is table service. Order drinks first, then food, and pay as you go or run a tab if the bar allows it. Children are usually welcome in pubs until about 21:00.

Check whether service is included before tipping. If it is not, 10% is normal in restaurants; in pubs, rounding up or leaving small change is enough.

The 14 EU allergens must be declared on menus, and coeliac awareness is high, so gluten-free bread is common in pubs. Vegetarian food is easy in cities and most pubs but limited in small villages; vegan food is good in Dublin, Cork and Galway and hard in rural pubs. Butter is used widely, so ask for oil if you avoid dairy.

Halal food is available in Dublin around Clonskeagh and Parnell Street and in larger towns; plan ahead on the west coast. Kosher food is very limited — contact the Dublin Jewish community before travel. For nut and shellfish allergies, tell staff when you order rather than when the plate arrives.

Stout and Irish whiskey are the obvious orders, but the pub is the point: a pint poured and left to settle, taken slowly. Tap water is safe to drink nationwide, so you can ask for it with any meal.

Tea is strong and milky by default; ask for it black if you prefer. Coffee has improved sharply in cities, and independent roasters are common in Dublin, Cork and Galway.

Ireland has little in the way of street food in the Asian sense. What it has is the chipper — fish and chips or a spice bag taken away — plus farmers' markets in larger towns, where stalls sell cheese, bread, smoked fish and hot food. Food trucks and market stalls are common at festivals and weekend markets in Dublin, Cork and Galway.

Food safety standards are high and tap water is safe, so the main decision is timing: chippers are busiest late, and market stalls sell out before lunch ends.

Book dinner in Dublin, Cork and Galway on weekends, when popular pubs and bistros fill early. Outside the cities, kitchens often stop serving earlier than you expect, so eat before 20:30 unless the pub advertises late food.

If you are driving, keep the pint for after the car is parked for the night — Irish drink-driving limits are strict and enforcement is routine. During busy holiday periods, some rural pubs close for a week or two; check ahead if a specific place matters to your trip.
