Actually GrubHub is an aggregator of restaurants that offer delivery. You browse GrubHub to find all nearby restaurants that will deliver (or offer take-out), you place your order through GrubHub, and then GrubHub relays that order to the restaurant.
In Square Pickup's case, this is an easy storefront for restaurants to offer their own online take-out interface. It looks like each restaurant gets their own white-labeled website, rather than just being a behind-the-scenes supplier to Square. You go to the website of the restaurant you want to order from and place the order directly with them.
