Great, I have 21 options for you!
Hi, I'm starving and would like to find a moderately priced restaurant in the centre please That's a lot of options, can you narrow them down for me by type?
{"__type": "Inform", "entity": {"__type": "Restaurant", "choice": "21"}}
{"__type": "Request", "service": "restaurant", "values": ["food"]} {"__type": "RequestAlternatives"}
Do you have a type of food in mind or do you want a recommendation?
