I really enjoyed the restaurant we went to last year - with the long tables. The food and service were very good and I remember having a good time there.
However I'm open to suggestions for other places. One thought is that there will be even more of us this year - maybe as many as 24 people including local friends, the mob from Madrid and other Spanish-based runners with our group of 16 foreigners. That may limit our choices of venue.
Anyway, booking a tables or tables early is a very good idea.
The harder the conflict, the more glorious the triumph
