This is probably the best HH location, in my opinion. Located inside the Rio hotel, it is big, spacious, clean, and the staff is always courteous. Don't let the long lines deter you because they seat you quickly! All of the food is delicious here and the prices are not bad at all. Portions are huge and again, the food is SO GOOD.
The only thing that I do not like about this restaurant is that they do not offer bottomless mimosas; maybe I am just a spoiled LA girl who is used to all her favorite brunch spots offering bottomless mimosas, but this is an absolute bummer. Still not enough to stop me from choosing HH every time I am in vegas :)
Definitely go and treat yourself!
