Well, that's true, unfortunately. There are a number of reasons, one of which is there's a r/e development right next door (where guys used to go to fuck).
It's still a fun bar, so by all means go, and steep in the history of the joint. But for bar-room sex, you'll need to go N on 4th Ave (which turns into Wilton Drive) to 6th Ave. You can't turn right, but you can turn left, immediately left again, and then enter a smallish parking lot for the Eagle. You must pay, or your car will be gone when you come up for air. It'd probably be most productive though, to uber it.
If you have any Leather gear, bring something so you can get into the Leather area ... it's reminiscent of the old days when the Leatherbars all had fantastic back(fuck)rooms.
Don't forget to hit Slammer, (sometimes called "321", which is the address on Sunrise Blvd). It's open from Thurs through Sun nights, from 7pm, and stays open until the last load is pumped up someone's gut.
