Bizznessman gave you the best advice. There are a lot of issues with partnerships and the one that looms large is that you assume his half of all liabilities in your partnership. Will this be a separate business from his gas station? Will you have other responsibilities other than cooking? Do you trust him?
One of the rules I use, is would I marry this person? If the answer is no, then skip the partnership and work out a different deal. Even leasing the space and cooker, running the business as your own, and splitting profits, if there are any, is preferable.
