Can I offer an explanation as to why some have enjoyed the food in this place and others haven't? (I haven't been yet-maybe in 3 weeks time)
The quality of the food will be very similar almost every time,but peoples
experience of it will differ because of one thing.
Without wishing to insult,I would suggest that those that enjoyed it are the types that like a bit of fuss and are easily flattered.There are numerous comments here about Josep,and how friendly he is - remembering names - being asked after -etc etc,and consequently those people will remember their experience fondly. I've heard it said countless times by folk over the 30 years that I've been coming to Spain - Pepe made us welcome/Juan made a fuss of us etc. The true quality of the food and service is masked by the overall experience.
And there are those that (like me) don't want any fuss or over familiarity,but do want decent food and service,and are not blinded to those requirements by being treated "specially" by the owner/proprietor.
That's just my view,having come across the same type of thing many,many times before.
We'll probably try it out in early October.
