Well, I think your $50 cover was for the music, and not just a basket with a few pieces of bread, right?
I'm not complaining about the cubierto charges here, but have trouble making sense of the relative charges. While 29 pp at La Cabrera seems reasonable because of all the wonderful tasting dishes, somehow 25 at Don Julio seems odd, for 2 white bread rolls. But both have lovely, real cotton napkins that must be laundered. Some less formal restaurants charge 15 for stale bread and polyester napkins that just slide grease around.
