Unexpectedly, we found a decent establishment right in the center. Pros: reasonable prices, decent food, a large, bright room. We'd passed it for about four years, thinking it was a cheap eatery. It turned out to be very decent. We ordered turkey in a pita with a variety of toppings. It was delicious and could be considered a healthy option. There's a selection of soups (3 varieties). There's a Baileys coffee shop nearby. It's decent. They also have good ice cream.
We also got a large pizza for just 15 euros.
The people around were very nice. The first room was full of older people, the second more young.
Recommended.
