Andres,

First of all enter with a big smile, If they really are Irish, the will respond. Order you favorite drink, being an Irish bar, alcohol will be plentiful, DO NOT TOAST THE QUEEN OF ENGLAND OR ENGLAND IN ANY WAY, this is guaranteed to get you dismembered and killed. Corn Beef and cabbage is a great dish, or whatever else you see on that menu suits your fancy. When you are finished, order Irish coffee. This is Coffee, Irish Whiskey and Whipped Cream. You drink the coffee and whiskey through the cream without stirring. ANd always remember next to Christmas and Easter, St Patricks day is another National Holiday. Enjoy Amigo and Happy Shamrocks to you
