I went a week ago and had a good time. Nice ambiance, if not a bid crowded to walk around. It was cool to be able to bring drinks back to the record/book store in back while waiting for our table. On to the food - tapas style and good - maybe not as authentic as a Taberno de Haro or Estragon - but similar quality and pretty god portions for tapas. The chef's plate for cheese and charcuterie was surprisingly big - I was more impressed with the charcuterie (jamon, chorizo, two other meats) than with the cheeses. Somehow the cheeses blended together. The Moroccon meatballs were excellent - the citrus salald nice - the chickpea soup was nice and warming (though harder to share). The chorros with chocalate (similar to Toro) are always a fun way to finish a meal. Good beer list, all Spanish wine list (interesting).
Definitely a great addition to the JP scene, and a very cool vibe. Good to see an interesting combo (tapas/bookstore) work well.
