Fast way for exp and money

Hey im big show ( not really) and i found a cool way to get good exp and money at the same time

2 pokemon and make them hold lucky egg and amulet coin ( the pokemon with lucky egg is the pokemon u want to train the most, and the pokemon with amulet coin is the pokemon that still needs training but not as much) .
Have any extra pokemon in ur party if u wish.

Go to Restaurant le Wow in lumiose city, which is in hibernal avenue.
Ask for double battle meal.
Follow the amount of turns they say to u ( the order of turns is 2-2-3-2-2)
The first 2 battles with amulet coin will grant u 20,160 pokedollars with amazing exp for party pokes and lucky egg pokemon.
Next 3 battles wont give u as much money, the amount the u will be given for the remaining 3 trainers is about 8500.
Make sure u follow the turns it takes, and try not to make ur pokemon faint.
After those 5 battles u will be given balm mushrooms, and if u had 11 turns total and 0 pokemon faint u will get 25 balm mushrooms which equal 156,250 poke dollars total. But for one balm mushroom is 6,250 pokedollars.
