Keep in mind you usually hear the "squeaky wheels" on threads like this...the thousands of people who liked a place & had good experiences usually don't post! So, if you can't get in anywhere else, you just might enjoy it anyway. We were kind of wondering when we saw all the bad reviews (after we'd booked it) but decided to try it anyway. We liked Hollywood & Vine...were there in May 2008 (just almost exactly 2 months ago.)
We did not encounter any of the problems people have put in bad reviews of the place...
It was clean, the hot food hot, cold food cold, great variety of everything, foods were constantly re-plenished. Spills cleaned up immediately. De-lish desserts, and the service was good. Check in went smoothly for us. It's a buffet...the food was not gourmet, but it was far better than all family-style national-chain buffets we've been to. I'd put it on par with a really good casino buffet. Yes, it was busy. Yes it was noisy...but no more noisy than any family buffet we've ever gone to anywhere.
