My wife and I go there on occasion. Fun place to go and play, but if gay would make you stay away, hey!, stay away because the majority of the restaurants and bars in Key West are gay owned/operated.
Which is to say, if you're a tighty righty, anti-gay, right wing whack job, you'll be shocked by the decadence of a society gone flamboyantly queer and will be likely to barf up your eggs Florentine a la Key West when your two gay waiters include you in their morning b!tch fest.
Key West is great...if you're not a typical denizen of the up-tight! Right wing world of PARF.
