E-8T

E-8T is a food recommendation Chatbot built using Node.js and the Microsoft Bot Framework. Natural Language Processing is handled by LUIS.

If you're starving and would like recommendations for food in the vicinity, look no further. At the moment, E-8T will make recommendations from HungryGoWhere when you submit your location.

E-8T is available on Facebook Messenger, @e8tbot. Note that Send Location only works on mobile.
