Yes! For example, you can leave instructions to have our delivery person call you upon arrival. When checking out on Grubhub, you’ll have the option to save any delivery instructions for that address, and if you need to make edits, you’ll have a chance to do so on the checkout screen. If you submit your order without special instructions, but would like to add them later, you can call us directly. If you need additional help, please contact Grubhub’s Customer Care by clicking here or give them a call at (877) 585-1085.
