there is always scope for tourism in dubai, round the year. if u r a moslem (are u?), they will not let you in at the night clubs, pubs and bars during ramadan (they check ur id). i find it hilarious when they ask for my id and enquire if i'm a moslem.

no public eating and drinking (not strictly enforced).

most restaurants and eating places remain open during the day, but they are discreet.
