Considering the location this IHOP stands out as one of the better ones in Las Vegas. I think its proximity to the Strip lends a hand to how busy it is most of the time. You can come in this IHOP any day of the week and at any time and you will find quite a few patrons.
I've been here late at night after clubbing on a few occasions (many years ago). Most recently I went with my husband for a mid-morning breakfast on Saturday. It was busy, they had all the sections open and plenty of wait-staff to attend to the amount of patrons.
I ordered an omelet of some kind, my husband ordered something similar. IHOP's menu doesn't change much, besides their addition of specials, which usually run congruently to whatever kid's movie is out at the time.
Our food was decent, came out quick enough and the waitress was nice. Overall, it was a generic IHOP visit that I am sure is within its corporate restaurant standards.
