How to come out to a gay friend? Advices?

Hi Guys, My friend (straight male) and I (gay male) are going to meet his friend in another city in holidays. This guy came out to my friend last year. And my friend told me later , I guess because I am also gay. This guy wants my friend to keep his identity as a secret ,which I totally understood. I am kind of half coming out now, aka my family and close friends know. I am looking forward to meet this guy and also want to tell him I am gay too. However, I do not want to throw my friend under the bus, even though this guy probably will understand and forgive him. So how to give him the signal that I am also a gay politely? Invite him to gay bar?Any advice? Thanks
