Congrat's on your promotion!!
Getting an apartment in Fairfield would be nice... There is alot in that area. Me and my son Go to Jungle Jim's alot... it is Large Grocery store that has food from all over the world. Route 4/Dixie highway has ton's of places to eat and shop, car dealers, pet stores and much, much more.
I currently work in Forest Park myself so if you need more info contact me directly. I would not live in Forest Park, but I highly recommend Fairfield. It is actually Butler county. Forest Park is Hamilton county.
I live in Colerain Township but it has it's bad and good areas. Whereas Fairfield I would say all good.
The closest Mall would be Cincinnati Mills Mall but it's going to close down soon, it's only a few anchor stores left.
The Mall to go to would Be Tri-County Mall and if you want High end it would be Kenwood Mall.
I know nothing about hanging out like bars or clubs. I do know there is a club call Metropolis in the Back of Cincinnati mills Mall but I have never been. Well good Luck
