This is a composite review from the first four or so visits, and deciding on a 4 or 5 star final rating was slightly hard, as this is a firm "4.5". We first tried this place due to a Groupon deal and returned due to a good first (and later) experience(s).
The pluses: Good food Cheap happy hour drink specials. Cute, friendly waitresses Ginormous big screen TVs in the east room Good food specials. Decent slot player incentive program.
The minuses: Gamblers and regulars get the lions share of the staff's attention (minor gripe)
If we are heading to the strip for an early evening show or something, we usually stop in at Sagos for some happy hour appetizers and and a couple happy hour drinks. Service is good and the price cannot be beat.
Just got an invite to their NYE masquerade party. $50/men & $20/women for open bar/food/free limo ride home. I am getting a little old for that, but I am tempted..
