Great strong coffee everywhere, food choices and quality is top for such a small place. You don't need cash, all places accept cards. It's full of tourists though and the city is tiny. So plan tours!!
If you're visiting. Go to BONUS and stock up on cheap and tasty food! This is the only place to get real Skyr, delicious and filling high proteinyogurt that comes with a spoon, great for excursions!
There is no exchange place in city and hotels. Only banks will do the exchange. You can also get a city card for 24-48-72 hours and some museums and poolsand public bus are free. Public bus cost 475
