People haul all manner of booze down there. When you first get into Supai there's a place that sells Ice cream. Then a little further along, there's the restaurant. One Indian taco is enough for you with some left over to share with one of the dogs that hang out there.
One more time I'm gonna say it: Don't ever take your own dog to Havasupai. The rez dogs may attack it. I have witnessed this. The dog that was attacked was paralyzed and had to be helicoptered out. (These rez dogs won't attack you, however.)
