Casa Colon is near the Plaza del Humilladero in the heart of the city. The decor inside features white walls with wooden accents. The venue is lively and bustling. It feels like a place where most locals come to relax and socialise. The service is excellent. We were attended to by Fuensanta, who treated us superbly. She took our orders and ensured the tapas choices were brought to us promptly. The drinks are superb, and they also serve gluten-free beer as a bonus. I had the tacos for tapas, which were very tasty. Even as someone who prefers a quieter venue, I could appreciate the lively Spanish atmosphere of people socialising. It's a lovely spot to unwind and enjoy good food and drink. Highly recommended.
