I'd echo most of the statements upthread. I really enjoyed Nobu on my one visit. $50 per may be a bit low for Nobu, and maybe a bit low generally for your quest.
Nothing says Bachelor Party more than steak, no? I've had a couple of good meals at Hard Rock's steak place, AJs in years past.
I had my Bachelor Party dinner at the Circus Circus Steakhouse. From all I've read, I think it remains a great choice for something not quite in the fancy-schmancy vein.
Golden Steer is very old school, again not the top tier of steakhouses, but a very cool place. Worth a consideration.
I've always enjoyed Border Grill and Chinois, places closer to your stated price point.
There's the new BIG imported Munich beer hall (Hofbrau) about across the street from Hard Rock. Seems like a good place to have on the itineary.
