Former Daytonian here (Kettering), now in Atlanta. In no particular order:
Pine Club - great steaks + a good burger.
Christopher's (Kettering)- home cooked food. good stuff.
Tanks - great burger and fries. One of the best chilis in town too.
El Meson - Spanish fusion. excellent.
Thai 9 as stated above.
DiSalvos - especially the DiSalvo Deli and their incredible Meatball grinder.
Jay's Seafood - heard it has gone downhill a bit. It used to be very good.
Paccia - see Jay's above.
Burgermaster - good stuff.
Golden Nugget - I remember the Country Omelette special...omelette stuffed with sausage, cheese, potato and onion, and then covered with sausage gravy (heart attack special).
Hickory on Brown (I believe different than Old Hickory on N.Main - I think they used to be the same company, then split). It should also be noted that while Dominics is gone, the Pine Club and Hickory both have similar salads, albiet with a lot less garlic. Speaking of Dominics, a friend of mine in Atlanta is a Mantilla. Go figure.
As for Wa Fu, I never ate there, but remember going down to the old Walnut Hills in college - we always joked that Wa Fu was a drug front. I knew many people who were towed from their lot.
Marions, Ron's, or Cassanos. All good, but with Marion's make sure to go to the Shroyer location and order your pizza from the old ovens (this applies to all Marion's). To get a good Cassano's pie, go to the main location on Stroop.
Milanos - not the same as it used to be, but still good.
I agree with the poster above that the best burger around is Crabill's up in Urbana. I've done the whole Crabills, Kewpie's (in Lima) and back down to Greenville for Maid Rite. Good times.
Chicken Louies was good as well - I remember when it was Lou's Broaster Hut.
Two good breakfast places that closed down last year: Chili King and the Breakfast Club.
