We ended our afternoon here after touring the Castel Sant'Angelo. The staff worked hard and we had good service. We only had some drinks and snacks. We actually paid at the end and gave a reasonable tip. She was extremely appreciative and brought us a smoked salmon sandwich, that was quite good. The waitress told us that normally she has to get paid at the delivery of service due to the fact that so many tourist eat and run. Shameful. I'm not sure why we weren't asked to do that, perhaps we looked trustworthy? I can't recommend this place for a meal, as we only had snacks. I can recommend this place quite highly for the view and to relax. Considering the tourist location, I didn't think that 32 Euros for our group that had 6 drinks was excessive.
