If the Electric Umbrella isn't busy and has plenty of available outdoor seating, the CMs never seem to mind if people sit there and eat food they brought in themselves. Obviously this isn't a good idea if there aren't enough seats for the paying customers, but it should be fine as long as it isn't crowded. Also, there are some outdoor tables, with shade umbrellas, I think, just outside the counter service place behind the Japanese Garden. Again, as long as the place isn't busy and the tables are unoccupied, that would be a nice place. It's a very peaceful and attractive setting, right by the Japanese garden and the waterfall.
