Most folk eat "real food" , although a few use gels.
I think the best thing is to go with real food to start with- think of what you'd like at the end of a marathon- that's the logical thing to be eating after about 20 miles, as far as I can see- I go for flapjacks and percy pigs ( or Clif bar and shotblocks/ honey stinger sweets) to start with, then add in crsips/ chocolate milk after about 20 miles.
Eventually you might need to revert to gels if you gut decides it's had enough, but usually you are going slowly enough to manage to eat properly.
Soem people eat the strangest things- cold pizza, pepperami, fish n chips, etc- you really need to try out a few things on a very long run, and see how it goes, but be aware that late in the race, anything can happen!
At most ultras there is either a drop bag system, and when people go through, they leave behing whatever was not needed from their drop bags on a table, which you can just grab stuff from- so if you have a sudden craving, you might find something that suits you on the table.
