Have tried several methods described but not winning. Here is the value ofthe var valuesEntity (this is from Luis integration into bot framework). 
I have not found a way to interrogate this var so that I get a variable with the value of Venue - in this case Bakery.

```
{{
  "$instance": {
    "Venue": [
      {
        "startIndex": 13,
        "endIndex": 19,
        "text": "bakery",
        "type": "Venue"
      }
    ]
  },
  "Venue": [
    [
      "BAKERY"
    ]
  ]
}}

```
