What a fantastic place for breakfast. First time over the weekend and I arrived right before the crowd. Super friendly staff, excellent service and great menu options. I love the mini breakfast. It was just enough to start my day. Fresh hot coffee and a clean restaurant. Service with a smile was refreshing to see. The staff seemed like they were family.
