My husband and step-son and I will be spending a week in Spain at the End of November. We'll be in Madrid for three days and Seville for three days. My son is an adventurous eater...loves Cuban food, fish and seafood in general. Can anyone recommend some great cafe's, restaurants etc... Not looking to break the bank. I'm always looking for what I call cheap and cheerful. The places the locals would eat on a regular basis. I'm not opposed to one or two expensive places as well.
