Presuming you mean the one at RPR? If so my wife and I did this last year and it was good fun. You get a photo outside with one of the Minions and then go into the breakfast, which is a buffet, you get seated with other people on big tables. Later on all of the characters come out, Gru, Dave, the girls etc and you get a chance to have photos with them - THese are not official photos so a CM uses your camera or phone etc.

Enjoy it, it is a lot of fun, didn't get any strange looks at all with us being 2 adults and no kids!
