This is one of my favorite restaurants. Delicious food that shows a lot of creativity, coupled with outstanding service. Every day there's something new and interesting. The food is lovingly crafted and you can tell that someone with serious culinary chops really put their heart into it. Despite all the skill on display, it never comes off as elitist or exclusive. Fancy, but totally down to earth. Reasonably priced too, especially the menu del dia.
We went here more than any other place during our stay in Girona. It's the kind of place that is so special that I will keep returning throughout my life, and when I'm far away, I'll think of it with longing. It's that good.
It is however quite popular, so make a reservation the day before. You are unlikely to find a free table if you just stop by. This is true of many restaurants in Girona, but for what it's worth, you should get a reservation.
So there you go. I've had some of the best meals of my life here, and I think you might too. Enjoy.
