For traditional restaurants, what percentage of orders are for delivery (using Doordash, etc)? Excluding pickups where the customer comes and picks it up himself. I can't imagine it's even close to 50%. I don't know the patterns of regular folks, but for me the prices in general have crept up enough that's it rare I want to try some new place - unless I get multiple strong personal recommendations for it. You can forget about paying extra for delivery to home!
