Had breakfast at the Nano Cafe last weekend and really enjoyed it. They have a really wide selection and the service was great - really attentive and pleasant.
It's certainly not much to look at (in the Albertson's parking lot) but the patio is actually pretty nice on a wknd morning
If you go I recommend getting something to accomodate the fresh salsa. I don't think I've had any better in southern cal in the last 6 months or more - I would go back just for that.
PS - there's another location in Monrovia but I have yet to try it
