For a recent tapas party that I was cooking for a fairly large group of friends and family, I stocked up on tapas cookbooks, and this was among my finds. Though the two recipes that I did end up trying from this book (clams in piquant tomato sauce and lamb brochettes) both turned out satisfactory, there wasn't much else that I wanted to try, or that didn't look better in a different book. There's lot of "filler" here - 4 "different" empanadas (though the only difference was in the filling), mussels and clams with the exact same preparations, etc.
The repetitive recipes, though, might be good for a beginner cook who has limited experience in substitution and other doctoring techniques, but for an advanced cook, this book seems overly basic, somewhat lacking in inspiration, and really just not the best buy for your money.
Try the El Farol cookbook instead... you'll be glad you did!
