Reviews
Incredibly, this is the best breakfast in the city, hands down. I go to Sunnyside nearly every single weekend (and I’d go more often if I could), and I am consistently met with fantastic service, generous portions, and the best chicken fried chicken I’ve ever had.
They maintain a great staff, and depending on the day, I know nearly every servers name. Sunnyside feels to me like a second home, where you know the people serving you and you never have to doubt that anything on that menu won’t be delicious (though, I am a creature of habit and my order is fairly consistent).
Though this may be less important to some, another contributing factor for why this particular Sunnyside restaurant exceeds their other locations is that fact that they are a Coke restaurant whereas all others are Pepsi. That, and as I mentioned before, their kitchen staff at this location is unmatched.
A few years ago this location sustained a little fire and smoke damage from an outside patio heater, and was closed for a few months. It was painfully clear that the other Sunnyside locations did not match this one. Even after moving within minutes of Sunnyside’s Edmond location, we still find the trek downtown worthwhile.
While I have been here countless times, and have been singing its praises to anyone who has ever asked me where to get breakfast in OKC, I thought it deserved an honest, public review.
I sincerely appreciate the hard work this restaurant does in creating its atmosphere of excellence and accessibility, and I can’t wait to see their excellent staff next weekend!
The food is absolutely phenomenal—hands down one of the best breakfast/brunch spots I’ve ever visited. Every bite was fresh, flavorful, and clearly made with care. This is the kind of place that reminds you why breakfast is the best meal of the day.
What truly sets this diner apart, though, is the staff. They are incredibly friendly, attentive, and genuinely kind. From the moment you walk in, you feel welcomed and taken care of. Their warmth and hospitality elevate the entire experience.
While the atmosphere may not be flashy or trendy, it doesn’t need to be. What it may lack in eye-catching decor, it more than makes up for with outstanding service and unforgettable food. If you’re looking for a delicious, satisfying breakfast served by people who truly care, this is the spot. I’ll absolutely be back!
