The former Texas A&M football superstar is getting into the hospitality industry ... opening up his very own watering hole in his old stomping grounds of College Station.

The place is called Johnny Manziel's Money Bar ... which is a clear nod to the famous nickname he was given after getting suspended for selling his autograph.

Of course, the business move makes perfect sense -- Johnny hasn't been shy about his love for having a good time ... and recently revealed in his upcoming Netflix project he once went on a $5 million bender.

"I thought I played better the harder I partied," Manziel said in the 'Untold' documentary.

He also previously opened up on his NFL experience ... saying he felt bad for losing the respect of his teammates for his off-field lifestyle during his time in Cleveland.

Manziel -- who had a stint in rehab in 2015 -- is content with how his career played out ... and appears to be in good spirits post-football.
