Wine and strong alcohol are very, very, very expensive. Alcohol is served only in international hotels and totally unavailable in the city. If the guy wears a golden chain heavier than 50 grams, do not try. Shopping is a real thing in Dubai. At the end of February they have a trade festival, where they sell everything with little or no profit.
Food is another great thing.
Numerous restaurants of different cuisines offer the choice of food at rather low costs. A dinner for two may cost as little as 40 Dirhams, and the meals are so big, that you better order only one to avoid overstuffing. I cannot remember the names of the restaurants, since they are mostly in Oriental languages. See also Earth This Project Galactic Guide site owned by Alex McLintock .
