It's worth it... at least once in a lifetime. Sr. Luis Garcia takes care of the resvs. I think we got in by flattery & letting them know we'd eaten at the 'competition' (not that I'd consider El Raco con Fabes anything similiar at all - great restaurant/real food/totally different), but I think there's a bit of a competition between the chefs. Worth a try.

I also was told of a colleague of my husband's that got in with a 500E tip to the Arts concierge. I'll stick with flattery!

If you do get a resv, be sure & check out the drive there / length of time it takes / easier ways to do it, etc, before taking off for your dinner reservation from Barcelona! A private car & driver is highly recommended.
