Great stuff. Few points (which you may be integrating on the back end already)...
@Nosaaaa Seeing as you guys have reviewed restaurants AND their food, it'll be great to get some recommendations on specific food items.
For example, if I typed "I want sandwiches" or even just "Sandwiches", the bot can show me (in your preferential order) a list of places where I can get good sandwiches. Same goes for steak, salad, seafood and all.
These food items are from places you have visited already, so you'll have the data and it shouldn't be that arduous of a task to get the list of items together. I might be wrong.
Even better, the bot can ask "What would you like to eat?", then have options of food categories/items like "Chinese, Thai, American, Nigerian, Russian, Pizza, Burgers, Jollof Rice, Plantain, etc.."
Like I said, this is something you might be working on already, so yeah, that's that.
