I ordered foods online from this Vietnamese restaurant via Yelp. The app was user-friendly for ordering online. As soon as I entered this place, there were a guy with face mask tried to talk to me. I used body gesture to explain that I was there to pick up foods and showed him the order from Yelp app in my iPhone. He quickly gestured and pointed at the foods that they are ready to be picked up. Very quick service, of course, during the COVID-19 pandemic.
