Hy,
I visited Dubai two years ago during Ramadan. My company sent me to Dubai to handle our A/C OPS to Colombo (SriLanka) and Male (Maledives). In my opinion the people there are very open minded on other cultures and religions. To answer your question: Yes, alcohol is sold during Ramadan. Itīs a bit more difficult but there are enough bars selling alcohol. The only thing you should be aware of is, donīt eat, drink or smoke in public before sunset during Ramadan. They gonna take this serious. Most Hotels vave a serperate area, where foos and drinks are sold for foreign people during the day. If you have more questions regarding life in Dubai feel free to send me a private message.
yours,
