This spacious restaurant belongs to the 4-star Husa Abad San Antonio. However, you can eat here even if you're not staying at the hotel, and in fact a large number of people come here to do so, as it's close to Leon's hospital complex. At lunchtime, it offers a set menu for € 11 with very generous portions and very fast and effective service. I've been twice and I ate very well, so I recommend that if you're in the area, come here, rather than eating at the hospital itself (sure, the menu is cheaper there, but it's infinitely worse).
You can choose from 3 starters, 3 main courses and 3 desserts.
