If you want it perfect, the best lab around is Richard Photo Lab in Hollywood, CA. They do great work, but you pay a little extra for it.
I've used NCPS a few times and they do a great job too. Everything comes back nicely packaged and well cared for, they also do very very good scans for a great price.
If it's something you want done flawlessly by people who don't compromise quality them Richard Photo is excellent. I also use A&I down the street from them since I get a 10% discount with my KCRW rewards card, they are a close second to Richard.
