Here is a list of "Where The Characters Dine". It gives Peter Pan and Snow White at Cinderella's Royal Table for Breakfast and Lunch and Snow White for all three meals at Akershus. However it is not all the time. I think I have also seen Wendy at Cinderella's, but she is not on the list.
And I have never seen (or heard of) any of the dwarves at a meal.
Snow White joined us at the Akershus breakfast in Norway in August but no Dwarfs. She was not at CRT though. I think it's hit or miss. You can't guarantee at either place.
As the others have mentioned, Snow White does appear at some of the Princess meals, but is not guaranteed. The dwarfs are not currently regulars at any of the character meals.
Peter and Wendy do show up every now and then at CRT, but only show up if one of the regular characters can't make it that day. I think Wendy has been more common than Peter there lately.
I've seen Snow White at CRT once and Akershus twice. I've seen Wendy at CRT once. The dwarfs are extremely rare, and the only time I've seen them, besides Dopey is at MNSSHP.
Peter Pan and Wendy earlier. I don't know of a restaurant with them but there is a Family Magic Tour where Wendy and/or Peter usually/sometimes participate. It's a type of scavenger hunt where the participants have to do odd things around MK. You may have seen groups walking backwards or like ducks around the Kingdom. If so that was the tour.
It's probably not right for really young kids though.
1) There are no eateries with the Seven Dwarfs.
2) During meal times, they are usually working in the mine.
3) You know -- heigh-ho-ing.
4) Besides, they are not well suited for restaurants
. . . can you imagine the hygiene problems with Sneezy?
. . . can you imagine the tripping hazard of Dopey?
. . . can you imagine the anti-food remarks from Grumpy?
5) You get the picture.

Awww-Dopey's OK. We ate breakfast with him at 1900 Park Faire about 10 years ago. He didn't trip once, at least not that day. Boy, I wish he'd return. A character meal with all the dwarfs would be so much fun.
