Truthfully the food was good and the portions were amazing even though my drink was only filled halfway up. The real issue lies with the workers. They are rude, take forever ever to fulfil your order (as a result of this the line was halfway down the airport, I've seen boarding qués that are shorter) and the restaurant itself was filthy, unhygienic and unsuitable to consume food in as the workers don't even bother to clean the tables. Also, we were travelling with a celiac and there was no gluten free options available and they were forced to pretty much starve (in saying that Bilbao airport as a whole shares this issue as there were no alternatives so the blame doesn't exclusively lie with burger king to be fair). I am a huge fan of burger king and this has not changed my opinion of the company as the issue lies with the workers and not the company. Please sort this out.
