We have just returned from 2 weeks at the nearby HPB site, and we ate at the Orone on four evenings - including the last evening as we thought it was the best. (Exactly the same as last year!)
Excellent fish soup starter at just 2.5 euros. 4 or 5 years ago when we first ate there this was 4 euros but all prices are now down by 33%, due to the recession.
Tuna steak, chicken in orange sauce, baby squid (chipirinos) are all wonderful (especially the baby squid!).
Mix of locals and tourists with a good atmosphere.
Give them a try - you will not be sorry.
