One of the most important things is capital and time availability, which I do not have at the moment. However, I am trying to reach an agreement with a family member, to temporarily associate us. I think things are on track.
You have described a key point for this type of business, what is offered must have a good taste for the palate, so that customers want to come back for more. It must be delicious!
Thank you very much for the clarification, and something you have described is very true, the food that is sold outside the restaurants, are more economical and have more portions. I suppose that the quantity and economy is related to the cost of services and the local, that the ambulates do not incur in them.
