As someone who has lived in Spain and loves the culture and the food, I am picky about my Iberian culinary adventures. And as much as you'd think tapas would be a fantastic choice for a meal, for one reason or another the whole concept often tends to get lost in translation with the food barely resembling its Spanish counterpart. Having been disappointed by another Spanish restaurant in Scottsdale that I won't name here, I was cautious about Papa Frita as I got there for my birthday.
Luckily the place was a pleasant surprise! The mood was great, great lighting and atmosphere. Our party of 20+ was accommodated with no problems and set at a large table in the middle of the floor. Flamenco dancing was in full swing. We settled for a taster menu and got about half a dozen different tapas each leading up to the seafood paella. While the bill was pretty pricey (may be 3x what it would have cost in Spain), it was pretty much in line or even a bit less than a typical Spanish restaurant.
Overall, good stuff. Great for very large parties too, as it's difficult to find places like this in Scottsdale.
