spend about QR100 on ingredients for a dinner meal... so as an example, you could probably feed a family of 6 on shwarmas and fries for about Qr100. That would give you about 8 Shwarmas and 2 large fries plates and drinks.

If you eat from cafeterias instead of Macd's or Burger King it will be way cheaper, with a Burger being only 6QR and a plate (including fries and salad) about 10QR.

If you look in the right places you can find food much more cheaply than you would a the places you would normally frequent. Portion sizes are quite big at these small out of the way places.
