To get only restaurant names use below code.

dbReference = Database.database().reference()
dbReference?.child("Restaurants").observeSingleEvent(of: .value, with: {(snapshot) in
for rest in snapshot.children.allObjects as! [DataSnapshot] {
            print("Restaurant Name:\(rest.key)")
        }

})

And to pass all data using StoryboardId use below code.

dbReference = Database.database().reference()
dbReference?.child("Restaurants").observeSingleEvent(of: .value, with: {(snapshot) in
for rest in snapshot.children.allObjects as! [DataSnapshot] {
            print("Restaurant Data:\(rest)")

        }

})

Put this in your And declare data variable in destinationController like below:

var data = [DataSnapshot]()

You have to performsegue from didselectRowAt like this.

performSegue(withIdentifier: "segue", sender: self)

And you can pass the data of selected item from the below function.

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let index = CategorytableView.indexPathForSelectedRow
let indexNumber = index?.row
print(indexNumber!)
let VC = segue.destination as! DestinationVC
VC.data = [rest] . //You can pass here entire data of selected row.

Just use below code to get parent node name.

 ref = Database.database().reference()

 ref?.child("Restaurants").observe(.childAdded, with: { (snapshot) in
    let rest = snapshot.value as? String
// snapshot.key is give you parent node name
        print(snapshot.key)
    }
})
