In Chicago a lot of restaurants refer you to Grubhub if you want delivery. If a restaurant lets me order directly from them I do, but sometimes resort to Grubhub. It's a great idea, until you have to contact their customer service. If a restaurant doesn't deliver your food or if the grubhub driver goes AWOL (both have happened to me more than once) and you have to contact them, their phone wait times are very long, and their support is bad. They don't refund money even when they say they will, they promise you free grub coupons but do not send it. They are not very polite. It sounds like they have 6 scripted responses, and when you ask anything off script they're very rude.
