Packaged Facts notes that full pre-COVID-19 recovery by conventional and casual dining restaurants might not occur before three years. Only slow growth in these sectors is anticipated with numerous permanent closings.  The May 15th article projects that twenty percent of full-service restaurants may close permanently as a result of the prolonged COVID-19 restrictions and subsequent economic recession. 

Fast-food chains will be affected to a lesser extent than full-service restaurants due to their reliance on drive-through and takeaway.  On-premise dining will be restricted by social distancing and a reluctance to patronize restaurants even if COVID-19 restrictions are lifted.  Only with introduction of an effective vaccine of proven efficacy can there be a restoration of restaurant traffic.
