Located inside Caesars Palace, Hyakumi has teppan tables (large, flat cooking surfaces so the chefs can prepare your food right in front of you; basically Benihana). We opted for the teppan table. They have regular tables as well that feature hot dishes and sushi. Unlike Benihana, Hyakumi has a wide variety of teppan tables (for groups both small and large). The decor is touristy Japanese--like something you would see at Disney World.
It is a little on the pricey side (though in Las Vegas, there are a lot of places much more expensive), but they do have specials where you do get a lot of food for your money. The special I got came with soup (meh), fried rice (not bad but kind of bland), and stir fried vegetables (the worst part of the meal; all you could really taste was the bean sprouts).
The main entree was filet mignon and lobster. The quality of the meat and the lobster was actually quite good. The problem was that it was just kind of on the bland side. The chef also didn't get a good color on the meat. It was kind of gray--boiled instead of seared. Maybe the teppan surface was not hot enough. For dessert, the flavor of the coffee ice cream was too strong.
Hyakumi has choices other than teppan--maybe those are better. But for teppan, it is a little below average for the price you pay. You may be better off with Benihana (while they use significantly lower quality ingredients, it does taste better).
