Query with result null Firebase

Hello everyone, I'm having a problem querying the firebase database.

The bank is this:

        Mesa mesas = new Mesa();
       // Restaurante restaurante = new Restaurante()

        reference = ConfiguracaoFirebase.getReferencia().child("Mesas").child(NFC);


        reference.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot dataSnapshot) {
                Mesa mesas = dataSnapshot.getValue(Mesa.class);
                final String local = mesas.getLocal().toString();
                InfoMesa.setText("Você esta em " + local + " " + "na mesa \n" + NFC);
                // Após ler o NFC ele faz a busca do local

                Query query = ConfiguracaoFirebase.getReferencia().child("Restaurante").orderByChild("localRestaurante").equalTo(local);
                // outra referencia porem apontando para restaurante
                query.addValueEventListener(new ValueEventListener() {
                    @Override
                    public void onDataChange(DataSnapshot dataSnapshot1) {
                        Restaurante restaurante = dataSnapshot1.getValue(Restaurante.class);
                        final String local = restaurante.getLocalRestaurante();
                        final String nomerest = restaurante.getNome();

                    }

                    @Override
                    public void onCancelled(DatabaseError databaseError) {

                    }
                });
            }

            @Override
            public void onCancelled(DatabaseError databaseError) {

            }
        });
    }

In the first search I made to return the table location only by deleting the table node and adding tables again I was able to get the return, I tried to perform the same procedure but there was no change.

I will also leave both classes of my objects to have a better idea:

Restaurant.class

public class Restaurante {

private String Nome;
private String LocalRestaurante;
private String ID;
private DatabaseReference reference;

public Restaurante() {

}

public void Salvar(){
    DatabaseReference reference = ConfiguracaoFirebase.getReferencia();
    reference.child("Restaurante").child(getID()).setValue(this);
}

public String getNome() {
    return Nome;
}

public void setNome(String nome) {
    Nome = nome;
}

public String getLocalRestaurante() {
    return LocalRestaurante;
}

public void setLocalRestaurante(String localRestaurante) {
    LocalRestaurante = localRestaurante;
}
@Exclude
public String getID() {
    return ID;
}

public void setID() {
    reference = ConfiguracaoFirebase.getReferencia().child("Restaurante");
    this.ID = reference.push().getKey();
}
}

Mesa.class

public class Mesa {

private String ID;
private String Local;
private String NFC;
private DatabaseReference reference;

public void Salvar(){
    DatabaseReference reference = ConfiguracaoFirebase.getReferencia();
    reference.child("Mesas").child(getID()).setValue(this);
}


@Exclude
public String getID() {
    return ID;
}

public void setID() {
    reference = ConfiguracaoFirebase.getReferencia().child("Mesas");
    this.ID = reference.push().getKey();

}

public String getLocal() {
    return Local;
}

public void setLocal(String local) {
    Local = local;
}
}

One thing that I found very strange too, is the firebase have let me use the table class without its constructor.
