Dubai Restaurants
"Cuisine includes both traditional Arabic foods and international entrees, particularly European and Asian dishes. Safar is open 24 hours a day. Emirates passengers with more than a 3-hour layover
may be given a free voucher for a meal at Safar."
not sure why it says may be given (any conditions are not stated) - i recall reading elsewhere a buffet is offered but found no mention of it on EK site
