Welcome guam, good luck with the concession setup.
One suggestion I have would be to come up with some GREAT BBQ that is sort of familiar to local folks favorite dishes and make them even more special.
A dish that everyone loves, figure out how to add some smoke, and a little love.
How about some fresh local ingredients rolled up inside a fattie?
Attempt a BBQ sauce with some local fruits and flavors, smoke local meats but add "out of the ordinary" and hard to find spices. Internet ordering is great for finding specialty ingredients many people can't find, so a little goodness mixed with a little taste of home is always a hit.
Wish you success.
Also, it would be a great idea to take Jeffs 5-day smoking e-course, you will learn tons of great info about smoking.
