Most restaurants have been hit hard by the pandemic but pizza chains have shown greater resiliency than most. This is partly because of their business model that largely depends on deliveries rather than in-person dining. Customers are used to ordering by phone or by app to get their pizza. They already have the riders and the systems in place.
Others are slow to roll out a similar delivery system because they are used to serving people inside the restaurant. They rely on foot traffic that used to be reliable given their strategic location. Now people are no longer going to their offices and schools. They rarely visit malls.
If you are planning to put up a restaurant at this time, then consider a pizza place or something that is similarly resilient. Get the best commercial pizza oven you can find to create tasty offerings.
