There are some days that it's not worth getting out in the cold wet weather or leaving the office to grab something to eat. When those days come along, grab your phone and place an order on grub south or grub hub.
If you are in the Huntsville area, Grub South is a newer company that works with restaurants to bring you what you want. They are working to expand (they have a little in Madison now) but their Huntsville options are amazing.
Meanwhile, Grub Hub is great if you do live in Madison or anywhere in North Alabama. They have been around a little longer, and have access to a wider range.
