GF BISTRO. It would be a natural expansion plan for GF PATISSERIE. Will it happen? Probably not (unless one of you steps forward willing to do it).
Regardless, here is another dish I would serve at a gluten free restaurant. Tasty, easy to make and most people like it.
A German dish by origin, many variations on the items that go inside, but always the same. A great combination of meat, gravy and noodles. Home made gluten free noodles with GF PATISSERIE'S flour mix.
Don't ask for recipes, just wing it...like I did.
