We visited the Aqualdel Center bar last Friday with friends. We had an enjoyable time and very nice tapas meal (raciones) there. The atmosphere was indeed lovely. The guests were expats, holiday makers and Spanish families, a nice international mixture, just like how SC is. It was good to see that almost all the tables were occupied.
The kitchen is operational from 13:00 to 15:00 and 20:00 to 23:00. As Michael Lambert already mentioned, they serve from a simple bocadillo to paella. Beside tapas or sandwiches, you can also order things like pizza or a meal. Paella need to be ordered in advance.
Our friends, who are permanently living in SC, and us are feeling very lucky that we have such a good bar/cafe close by. I fully agree with Michael Lambert: we would highly recommend it!
