My recent excursion to Riyadh was uneventful because of work-related timings and managed the logistics for a six-person team. We did stop at one place, Mama Noura on Oleya Road near the Sheraton. Its a mainstay of inexpensive good eats. Three of us went and got some eats:

Large plate of cold mezza (one plate)
a Fruit Juice (they serve it unsweetened) (three mugs)
and a meat-based sandwich (meat kebab, chicken kebab, and shish tawook) (3 sandwiches)
Price: SAR 52 — $13.87 TOTAL
