Mimi's is a clean, solid diner with food that delivers what you expect without pulling any crazy punches.  While it has been reincarnated several times over, I wouldn't call what it retained particularly charm.  The atmosphere is friendly  but quiet with no music playing.  If you want a fried chicken breast that is not greasy, a good stop.
Review Source:Tired or Retired:
Mimi's is an old school hash-slinging palace. They have eggs, bacon, biscuits, chicken-fried steak, patty melts, etc.
Better like eating early, because as soon as the lunch rush slows down, the tired elderly waitresses, head out, and Mimi's shuts down by 2.
Nothing remarkable, but nothing dangerous either. Safe Breakfast standards. Not an unpleasant choice.
Day seven of our road trip to San Diego, stop 4.
With the disappointment of the Action Figure Museum's being closed for the President's Day holiday fresh in our minds, we went in search of downtown Pauls Valley for at least one experience we could take with us.
It was only 10:30 in the morning, and the town was pretty quiet. Being that it was the holiday presented us with a bit of a challenge, as almost all the businesses were closed and the streets were deserted.
I thought how cool it'd be to open a safety deposit box at the local bank. Like I'm some criminal trying to hide my money in all corners of the US, or put some memento of our trip inside it, creating a time capsule of sorts. But no, bank's closed too.
As I turned to the main street that would lead us out of town, I saw a great big sign that begged further investigation. Mimi's Restaurant. The sign said, "come in here, do it, it'll be cool!" and I busted a u turn to park right in front.
The metallic white shades were drawn so we couldn't see inside, and when I pulled open the door, I was surprised with what I had found. I expected 1950's classic with barstools, shake machines, and paper hats, but what I got was 1970's pragmatic. A wood paneled office turned diner, with second generation mismatched booths and an open service area smattered with appliances for convenience, not aesthetics.
Sarah and I weaved through the customers that were all somehow inside and half outside their booths at the same time, returning all the stares dead on with smiles and head nods, and plopped in a booth in the corner.
Now, we weren't that hungry, as just hours before our Oklahoma City hosts cooked us a massive breakfast. But we came in, we sat down, so now we must order something! But what was I in the mood for?
The old, grey waitress with her friendly eyes and big smile came up to us and asked what it was that we wanted. I replied with "a shake, vanilla," and her smile disappeared. "We don't have a blender."
I started to tell her that it was okay, but before I could finish saying so she skipped off and we could hear her whipping up a shake with an electric handheld beater.
What an awesome day!
A few minutes later I got my vanilla shake, and gave her a mad tip to which she exclaimed, "oh my! Thank you."
Tip: try the special of the day, it comes with FOUR of the six vegetables they offer every day! Surely, lots of food.
