Have only been here once (on a whim passing by), but I had my usual (everything w/ schmear, and an Americano to go. The bagel was huge & well flavored, and they serve Kean's coffe there. There was another party dining in & one of them got a bagel w/ lox & it looked pretty good from where I stood.
My personal fave Everythings are from Einstein's
Also , seconded on Break of Dawn. If you want a Breakfast Experience, look no further.
I have not found a good spot in OC, I usually just buy some lox and do it at home. The portions at Jerry's are way too small, so that's out. You might try Katella Deli, I know folks who swear by it for other things. Zovs does have the gravalox, but it is not quite the same thing.
But, if you want to try a twist on it, go to Break of Dawn and get the lox there. They serve it on a little crispy pancake thing and do pile on the lox. It isn't traditional, but it is good.
Shirley's Bagels has the best bagel in OC. I recommend their everything bagel which I have almost every other weekend - crisp outside, flavorful everything crust including a wonderful hit of salt. The lox are good as well but they have a weird system for ordering lox and bagels where they call it a "sandwich" and you get some potato salad on the side, which I'm sure other people might enjoy but I only wanted the bagel and lox. You order at the counter, though there are plenty of chairs and tables.

re: OC Mutt
I'll go along with this, but only if you get the bagels fresh. They re-sell their bagels to Kean Coffee and cold they are not a success. (I have issues with the food at Kean, honestly... but the coffee is so awesome that I don't care about the food.)
Buy the lox elsewhere, though.
This is just FYI - Because I've never had it there; however, if I wanted somewhere in Tustin, I'd put Zov's on my short list to-try:
... "Bagel & Gravlox - House-cured gravlox, red onion, capers, tomato with a toasted chewy
bagel and cream cheese"...
