You may try this :

var nonVeg = jsonData.Food['Non Veg']; // jsonData is json data which you have given above
for(var key in nonVeg) {
  for(var i=0; i<nonVeg[key].length; i++) { 
     var storeObj = nonVeg[key][i];
     if(storeObj['specialDeal']== 'true'){ 
        console.log(storeObj['Store']);
     }
  }
}

since we are interested in only Non Veg part of the JSON, we can store it to some variable
i,e. var nonVeg = jsonData.Food['Non Veg'];
now we can say nonVeg as a object alone. in this object it has few more objects, so lets iterate through each one with for loop, and store it to a variable called storeObj.
since storeObj has many key-value parametres lets iterate each storeObj with for loop.
and finally lets check whether the specialDeal property has a value of true? if yes then console.log its ‘Store’ property i,e. storeObj['Store'].
