st. Brodeux resturant and milkshakes

I have 2 questions..

The first is does anyone know how to beat St. Brodeux restaurant? I have been trying and trying and i can't raise the 2500 that i need to win. I'll take any ideas I can get.

Also has anyone else noticed that the milkshakes don't come as often as they say. They say it comes after so many matches yet I only seem to get 1-2 a level..
