In Dubai, at least the Pullman Deira City Centre has a nice executive lounge. I was there about a week ago. Breakfast in the morning, some afternoon tea, and cocktails in the early evening. Hot and cold drinks served at all times by very friendly wait staff. At some point they also had dates and Arabic coffee, which is a delicious combo! The lounge attendant was able to help me out with electrical adapters and check-out. This was the best hotel lounge I'd tried (until I went to the Sofitel in Abu Dhabi the day after)!
