" Fully IMC " or perhaps " Vertigo "
Well, if it was a Western themed bar I would have to call it the “draw bar”.
If it was on a beach I’d call it “The sand Bar”.
If it sold ice cream I’d call it the “Publick bar”.
If it was somewhere near the overshoot or undershoot I’d call it “The Crash Pad”.
If it was on the North side of an East west runway I’d call it the “2 and 8, right?”.
If it was solely for pilots I’d call it “Braggers”.
How about EASA – that bars everything!
If it were a stripclub, I think ETOPS would be appropriate 
With so many new folks having joined since 2014 maybe time to tap into some fresh creativity!
Bar None 
If it was a mobile bar – The Fuel Truck.
The bathrooms would be “The Jerry Can”.
Last orders would be called by “Announcing Final Approach Fix”.
And if you wanted a double you would order a “Twin”.
Bucking Bar
Which has to serve a drink called Wolfram of course
Outer Marker.
I’ve seen several houses with that name.
In German, the syllable “bar” can be adjoint to a word, and that is done quite regularly. For example “unsinkbar” means unsinkable. In this regard a proposal for a bar’s name in german is “UnfliegBar”, that means “unflyable”.
But I would choose fliegBar
