How is that a lot of work? Is it a lot of work if you really are looking for a restaurant where you can dine in?
On the delivery services, you can search all of the menus of places that deliver to you at once. If I want a club sandwich, I can find what 32 restaurants will deliver me a club sandwich. There is no other place I know of that will tell me what restaurants in some radius of me sell club sandwiches for dine-in, that I'd then have to cross-reference with which are available on my preferred delivery service anyway. It's a lot more work.
