There are plenty of good supermarkets here, with an excellent selection of toiletries. Bring enough to tide you over for a couple of days, but everything you need is here, and reasonably priced.

As for where to go, there is plenty of choice, and I can assure you, you will have no trouble finding a shopping mall here.

There are two mobile providers here Qtel and Vodafone. Both are good value and pre-paid sims are available simply by showing your passport.
