Kex Hostel Bar sits inside Reykjavik's most popular backpacker hostel and has become the most reliably-packed harbour-side bar in the city. Industrial aesthetic with reclaimed-wood communal tables, big terrace overlooking the harbour, and 18 rotating Icelandic craft beer taps.
The kitchen serves all-day food (burgers, fish-and-chips, Icelandic plates). Live music three nights a week. The crowd is international backpackers 20-30 and visiting Icelandic-culture tourists. Cash and card friendly.
