Well, not quite.
Some restaurant customers have a rather terse, no-nonsense way of telling you that what they are eating couldn't get any better.
And this N.Y. Times article provides a good example of that. A man named Frank Mancino had this to say about Brooklyn's Di Fara Pizza:
"It's like they dug up my grandma and she made the pie."
You tell 'em, Frank. At $5 a slice, that is very high praise. (But I'm assuming his grandma didn't charge Frank for a slice of her pizza.)
