The place was quite busy with both tourist and locals. Sandwiches were made fast with friendly service. Rest rooms were clean. The whole restaurant seemed very clean. It was a good, quick lunch. If driving though Oroville, I'd stop here again.
As far as Subway restaurants go, this one is very clean and staffed by exceptional friendly people. We eat at his shop 2-3 times per month and are always satisfied with the sandwich and the service that we receive.
