This is definitely one of the very good buffets in Vegas (I have sampled a few myself and considering the price it is probably the top one on my list).
Their food is very fresh and they carry a great selection of items from various cuisines.
I have been there for breakfast and brunch I warmly recommend the smoked salmon, the sausages and also the skewered pork (Brazilian style). For brunch they even have sushi (not too bad) and even kimchi.
Also, the place has a large selection of delicious desserts.
The reason I did not give them 5* is the somewhat high price ($20 for brunch and $15 for breakfast), but totally worth the money.
