My new favorite is finding Cincinnati mansions on Zillow that are time capsules of the late 80's and wow there are some complete legends

There are wet bars absolutely everywhere and I love it

I have expanded my search to the PNW where more of them have been updated (boo) but bless these people for preserving that curved, sunken couch and the wet bar

If it has...

Vaulted ceilings
Skylights
Carpet in the bathroom

Then it 100% has a wet bar in the basement
