Can Fabes and Tickets Dress Code
Can Fabes is one of the more formal and low key 3 star in Spain: for lunch in September, casual dressy would be fine (shirt/slacks even khakis, sweater would be fine for men). For dinner, I would go with a sports jacket for men but one probably would get away with shirt/slacks/sweater for men. Suit and tie not necessary.
It's a long story, but my husband and I went to Can Fabes for lunch once, several years ago, on our way to the airport. I had done lots of research into good food in the area, but had somehow forgotten that it was a three star place. Anyway, we were a little worried when everyone going in was dressed very smartly (it was Sunday lunch), we were wearing jeans and we didn't have a reservation.
They were absolutely charming - they were fully booked in the main restaurant, but they let us eat in the Espai Coch area (I think that's what it's called - it is a room that looks into the kitchen). This part of the restaurant was normally closed on Sunday lunch times, and the menu served in there was not usually available, but they opened it for us and we had the Coch menu. Fabulous service and they didn't once make us feel as though we were under-dressed. Don't get me wrong - I wouldn't turn up in jeans again, but I think they are very relaxed about what people wear.
