We travelled to Llivia just to say that we had been there. Cold and snow. Decided to grab an "early" lunch (at 1300 in Spain) We are glad we got a seat when we did. The placed filled up with locals to the point that they and to turn on the propane patio heaters so that people could sit outside and eat. We think it was that the food is so good as there are a few other cafes in the town that didn't look busy.
A good spot to stop get warm and eat lunch.
