Zero barrier. Everybody speaks English, though contrary to other replies _locals_ tend to speak with a distinct accent. There are also lots of foreigners employed in the hospitality industry - Spaniards, Hungarians, Lithuanians and others - their English is markedly better. Oh, edit - as others said, things are really quite expensive there, including food and drinks. Research before going. A breakfast of bread, butter, jam, a sausage and two sunny-side-ups can easily be 30 USD. A pint is 8-12 USD. A lunch of an unlimited soup and bread - 15-20 USD.
