One thing that the strip is lacking is quality traditional breakfast food at a reasonable price. So if you're visiting Vegas put OPH in your gps and discover what the locals already know, it's one of the best breakfast restaurants in Vegas.
No, it's not unique, in fact it's a franchise, but that doesn't change the fact that it's good. Try the potato pancakes with apple sauce, or the banana pancakes with strawberries! There are a million pancake variations to tempt every palate. And if you don't feel like pancakes they have a variety of other great breakfast fare including omelettes, crepes, and waffles.
Bottom line: good service, great food, reasonable prices.
