We are not supposed to bring in any food or drink into the Olympic sites.  Here's a list of foods that I have eaten at Olympic events (My Olympic Diet): DRY instant noodles, hot dog in a bun (pig in a blanket)—covered with ketchup on the outside, bread with corn and an unknown white sauce, a muffin, Snickers bars, plain butter cookies, ice cream cones & a popsicle. There are plenty of options for drinks—Coke, Sprite, Fanta, iced tea, beer (for the adults) all for 5 RMB (US$0.75), but good food is hard to come by it seems.  

Here's a picture of the complete menu. At the venues, a lot of these items might not be offered--like I've never seen sandwiches at any of the events I went to, but my Mom said she ate a sandwich and some sweet popcorn (the Chinese put sugar, not salt on their popcorn) at a Basketball match.  We've learned to eat a big meal before we head out (usually two hours before the event starts) and I bring my own granola bars in my bag!

There are two McDonald's on the Olympic Green, but the lines are so long that you have to wait over 30 minutes to buy anything.  After our third visit today in the rain, we finally managed to buy lunch at McD's.  Those hamburgers never tasted so good!  Found out that athletes have two McDonald's just for them, and it's all free—more on that next time as I write on the life of an athlete at the Olympics!
