We went to this place from a recommendation from someone at work that grew up in Madrid.
Although the drink selection was limited (no Cava), the food was great. For drink, I stuck to white wine (although they have a cider that they are known for. It was pretty good, but could only have two sips).
For food, the tortilla potatas was great (it was not just a simple tortilla), and the chicken was basically so juicy (it fell off). We also got jaman and some sort of cheese (almost tasted like guda mozerella). This was a great recommendation, and would definitely go back.
