I was extremely exited when I heard that Des Moines was going to get a Little Caesar's Pizza. The last time we took a trip to texas we planned our routes based on passing Little Caesar's. They have peperoni, sausage, and cheese Large pizza's ready all the time for $5. Oh and do not forget about the crazy bread (breadsticks). That stuff is to die for! They also have wings and you can special order any kind of pizza, but obviously they cost more.
I can feed my family of 4 for about $8. It is great.
The only downside is that they don't deliver, but at prices like this how could they!
