Ordering food on your phone is now a thing of the past thanks to the folks at Amazon. Amazon's digital assistant Alexa can now order food through Grubhub for you. With Grubhub having access to over 50,000 restaurants, Amazon has made the convenience of ordering food even easier. The one catch is that you won't be able to place an original order through Alexa, with only previous lu placed orders being able to be processed at this time.
