I'm a local illustrator / designer and constantly need stuff printed, usually last minute to boot. They're the quickest place I've ever been to for all the jobs I've taken to them thus far, and to be honest, they're always my first choice. They're always friendly, calm, and professional, a real pleasure to work with.
The pricing is phenomenal and if you're doing prints, you get a *much* better quality paper compared to other places around the valley. They also allow for small orders of things like coiled books and stuff like that, which is handy.
The only real downside is that they are only a Mon-Fri 9-5 type schedule but you can usually email them and they are great about communication and working with you. If you're not a human wreck on a weird schedule like me, 9-5 is not a problem anyway, really. :D
