Safety: The Landing (straight towards the river) is a "large group after dark" area. Otherwise, groups of 3-4 should be more than enough.

Now, the food: Head towards the park a few blocks straight out the main entrances. Pick a street, you're bound to find something. I know of a Hardees, a Jimmy John's, and a TGI Friday's out that way; there's an Imo's Pizza on the other side of that park but I don't know exactly where. There's also a grocery store or two and at least one Papa John's.

I don't know for sure about food carts, but if they're out there, I remember them not being your average hot-dog stand. (OK, so I wasn't there for a Championship...)

Note that I was there in Winter '09 (right after Christmas, to be exact) for a college-age conference, so things might have changed. But I never had any problems even going out as a group of one (other than the long lines...)
