We were here for a Yelp even and I have to say that I was impressed. I know that the staff and management will be on their best behavior during these events (after all they are basically a form of marketing) but still. This was the best service I've had at any Yelp event. Including some fine dining establishments.
The district managers (former owners before they went corporate) really seem proud of their work and their locations. The staff knew their stuff and they do temp their meat rather than rely entirely on a timer (which means that it is possible to get something that is not as overdone as most fast food locations).
The food all tasted great and there is a huge variety including interesting looking salads. And don't forget about the hidden menu items including... friend pickles.
In my opinion, this is one of my favorite fast casual places in the valley. I'd place them above 5 Guys and In And Out. And the prices seemed a touch lower than 5 Guys and you can get something from 4 Peaks if you want a drink too.
