O Face Doughnuts is within walking distance of my office so I might be a regular. My goal is to try the whole menu. They have a lot of variety so that might take a while. Thus far I've had the lemon rosemary, passion raspberry, almond joy, and a chocolate one I can't remember. I have not tried the regular/traditional doughnuts yet...I get too distracted by the sprinkles and whatnot. Right now the passion raspberry is my reigning favorite.
The one complaint I have about the doughnuts is that the gourmet doughnuts are a little overstuffed so you might have to eat them in one sitting. They are a little messy and might fall apart if you try to set them down. The coffee is not that great. It's not undrinkable, but I think they could definitely improve in that department.
Service is pretty good. In Vegas we get a little spoiled by the very professional service industry we have here and this place is no exception. The staff is friendly and attentive. They are happy to explain the different flavors and offer their recommendations.
Overall - thumbs up. You should definitely try this place out.
