Sky's is pretty good. I also like Mellow Mushroom's pizzas. I haven't been there in a while.
I miss the Shakey's that was on Davis Hwy across from the old University Mall. I had my first pizza from a Shakey's in Bakersfield, CA when I was a kid.
Of late, we have been ordering from a Pizza Hut carryout and delivery joint on Saufley Field Road, and have had good results. We only do this in a pinch, and because it is a few blocks from our home.
