I was on vacation in Las Vegas for a week. The cafe is located near some friends I was visiting. We checked out the place on 12/28/2009 at about 11:05 am. It was crazy busy. Only 2 people were working there, and they didn't take our order until after over 10 minutes of waiting. Then we sat around for about a half hour and finally got our food at about 11:45. The only reason I put up with the wait was because I treated my friends the day before, and it was their turn to treat me so I let them pick out the place to eat. (If I was there by myself, I would have left after 5 minutes since they didn't take my order.)
The food was ok but not worth the wait. If WaffleS Cafe is 2/3 or more full when you get there and a few people are working, I recommend getting food elsewhere.
I wonder if the good yelp reviews is why a lot of people are eating there. It could be a blessing and a curse...
