This is the original Diablos Cantina.. The Royal Oak one lacks the attentive service that Ferndale has. I enjoy a good meal at the bar and enjoying the bartender's company. Salads are terrific.
The wait can often be an hour to two hours long. To mitigate this, call their number to be put on their wait-list at least an hour ahead of time, and they will text you when your table is ready.
