At the University Center near UCI, there is a pizza place called Blaze. They allow customers to create a pizza that they make before your very eyes.
The place was packed. Luckily, the pizza makers move quick. I ordered ham and cheese for around $6.
I didn't have a chance to try it but my little one ate a bunch of slices so it had to be good. I did try their s'mores pie. You have to order this one
