While the services at the Club lounge on the 39th floor were great, the staff at the breakfast buffet on the ground level were not very attentive to customers' needs. I walked up to a waiter to ask him to bring me a cup of coffee. Never happened. Went to get it myself from the coffee bar. At no point during my quick 15-minute lunch did any waiter or waitress ask if I needed anything. I left the restaurant thirsty and had to ask the reception for a bottle of water before we headed out to the desert for sand duning. Disappointed by the restaurant staff's sub-optimal service. I should add the restaurant was only 1/3 full!
