Hi! - Doesn't sound good but I will add we've been going to Lanzarote nearly every year since 1993 and always go down to Playa Blanca at least three times for a meal and have never experienced anything as bad as this. Quite the opposite. When it comes to steaks their medium and well done seem to equate to our rare and medium but it does seem a little extreme to say you had no decent meals in two weeks.
