Corralejo, Fuerteventura, Canary islands:
Describes itself as a beer hall, and I’m stretching “pub” here, but it deserves entry for being the only place I found selling beer, as opposed to lager. No cask, but a good selection of keg and bottle from around the world; I had a Canarian IPA and a Oktoberfest beer.
Situated in the old town, in a square with other bars and restaurants. Pleasant staff, nice place to sit and drink, but not cheap: my 500ml IPA was 8 euro.
