Coco's is probably one of your better bets in Vegas for an affordable breakfast in Vegas. Aside from the "B" Food Safety Restaurant Inspection card rating (at the time of this review) posted at the cashier, this place seems to be pretty good and pretty affordable (no crazy inflated pricing) . They even have an awesome deal on burger's and fries for $4.99 which is pretty damn hard to beat anywhere in Vegas.
This became my regular breakfast joint considering that I could get a bowl of quality steel cut oatmeal with blueberries, bananas, milk & brown sugar for a few cents more than a small cup of water with oats from the local Starbucks. For a decent breakfast such as pancakes or french toast, it pretty much beats anything you'll find at your local casino in regards to value. I mean it's not "gourmet" food but it gets the job done at a fair price.
The service is pretty good considering. I never had any problems with the waitstaff, hostess or cashier. This will be my regular go to breakfast joint when I feel like saving some cash in order to splurge on other cool stuff in Vegas.
