OK, I realize budget and prime rib should never be strung together like that. But we've been on a prime rib kick here at home lately and I figured since I'm busy planning our May trip, I'd ask. Anybody know of really tasty, affordable prime rib anywhere? I'm not ruling out a buffet, but I'm open to suggestions! Normally, I wouldn't be looking for suggestions for cheap beef, but it does have a certain Vegas kitsch to it, right?
