As far the menu goes, stuff your guests with the best of street cart grub. Hot dogs that have been sitting out too long, stale soft pretzels and a greasy slice of cheese. Each of these items can be easily made bite size (remember pretzel tots?) which would make them all the more appealing.
And what’s a party without cake? These city blocks make the perfect topper and can double as a gift (as long as you lick the frosting off).
