I've always liked diners for their non-chain feel and the fact that their food doesn't seem so assembly line. Johnny's was great. I got a Reuben, which was better than any Reuben I've had in over a decade - that includes local and Cleveland delis. The fries weren't really my thing, but they have other sides that I'm looking forward to trying.
The service was outstanding. The staff were really friendly, and the owner came over to say hi after my wife and I had finished our meal. You don't see that kind of thing anymore, and I really appreciated it.
I'll definitely be back. If you haven't been before, do yourself a favor and give Johnny's a shot.
