I went to cascayo soon after arriving in Barcelona while I was waiting to check in to my Airbnb. It was not very busy, and the waitress mentioned that they are a newly opened restaurant. She was very attentive and helpful. We had mojito to drink which were pretty good. We tasted patatas bravas here for the first time and they ended up being my second favorite of our stay in Barcelona. For lunch I had the grilled chicken salad which was much better than expected. The chicken was well cooked and seasoned, and the olive oil was very fresh.
If your staying or live nearby, I'd say this is a great place to try out for a quick meal, drink or coffee. read more
