Our own restaurant!

I have been toying with the idea of quitting my job and starting an allergy friendly restaurant but I have no clue how to start a business let alone a food establishment. If anyone has experience,I'd appreciate any advice. Do you think there is a market for it?

I wonder how many families would drive the extra mile or pay the extra dollar to be able to share a meal out together or have ice cream for dessert together? I know I would! How divine would it be to sit down, order a delicious meal that we could all enjoy together! We can't eat out anywhere and an allergic reaction to McDonald's french fries led me to find they are made with milk! I started checking online and found that Burger King make theirs with wheat! Wendy's is the only place that has wheat/milk free fries but they fry them in the same "contaminated" oil with their other wheat & dairy products and I did not want to risk trying them. So many hidden hazards for my little girl so we play it safe now and avoid anything I can't read/verify the ingredients for.

Thanks,
Blessed Momma
