Hi everyone,

i serveived my first day in Riyadh allhamdulliah although i have had some much bad luck waited 2 hours for the hotel driver as they got my arrival time wrong but enjoying it so far had a couple of questions to ask if some one could kindly answer.

2). best place to go for suits shopping ? i have been told Riyadh Gallery by the hotel reception for as it has next and debenhams.

3). Best currency exchange near by for UK GBP ?

4). Where is the network meeting on friday ?
