What's the most deluxe sandwich at McD's nowadays? I think his best strategy would be to go for the fancy sandwich. (NOT the pentuple-quarterpounder. The one that's super special because it contains honey-mustard or whatever.) Probably chicken/fish instead of beef, since they don't brag about mass.

How much does a small drink cost? If it's $1, you're definitely hosed if you include drink money in the $50. I like with your idea of allowing BYOB.

I say the cost of the food is either split or goes to the loser. 'Course that changes the odds slightly.

edit: Make sure you specify WHICH McDonalds! Don't let him go to the airport to buy his food.

edit2: Also, specify that he can't modify the sandwich. No "BigMac Hold The Everything"s.
