How do I get travel agencies to send tour buses to my restaurant?

I'd like to get into the tour buses business with my restaurant, but I really don't know where to start. My guess is that I need to get in touch with the travel agencies that put together the holiday packages that include meals, and make a deal with them to include my restaurant in the package. What I don't know, is how to find out what local (Irish) travel agencies put together these packages for foreign tourists?|||Wrong - don't bother with the agencies - find the guides who work on the tour buses and give them free meals and drinks.
