Restaurant Food Delivery Options

What are your experiences with home food delivery? The only thing I’ve ever ordered was pizza, but now I’m interested in high quality meals delivered that I don’t have to prepare. I want to make a list for myself. So, if you have a list, please share w/contact info. Also, delivery fees and tips? Does the food arrive hot? This is an adventure for me, it’s on my 2018 “to do” list. Thanks!
