I'm leaving in exactly a week for Spain! I arrive in Madrid and plan on staying there, visiting Andalucia, and Barcelona. I realize that this is sort of a general question, but does anyone have any budget restaurant/tapas bar recs for Madrid, Seville, Granada, or Barcelona? I imagine that I'll be eating a lot of tapas throughout the trip, punctuated by a few great meals. If anyone has any suggestions I'd love to hear them. Thank you!
