I think it would be best to take a step back first of all! The passion is good, but you need to have a product that your customers enjoy, and then build your customer base.

Start at farmers markets, festivals, etc. and listen to your customers. See what they like, see what they don't like. If there's success there, maybe find a brick and mortar location where you can start your first restaurant.

It's a tough road, and it takes a lot of time. But if you stick with it, you can do it!
