Riyadh is growing by leaps and bounds and Pizza Hut is right there with it! No matter where I go around this city, it seems I'm never more than 5 minutes from a Pizza Hut. They seem to be doing huge business. They're extraordinarily convenient and the veggie pizzas actually have real fresh veggies on them.
Saudi Arabia's population is growing. Family sizes are large here. So it's real internal growth. Greater Riyadh is expected to more than double in population and size over the next 20 years. In the course of my work duties recently I had occassion to visit the ArRiyad Development Authority. They're in charge of planning major infrastructure works around the greater city area. They have some very ambitious looking plans for building a light rail network around the city. That's something this city really needs, a decent public transportation system. Given their ability to plan large scale projects, I have a feeling the authorities here are going to do a good job of it.
