There's the Lincoln. It's very kid friendly. I used to live a couple of blocks away, and since then, it has been a periodic convening spot for Saturday breakfast with about eight of my friends and their assorted munchkins. If we get in at 9 we can easily get a table big enough for all and room for running around. One of the group sometimes thinks the food is too greasy, and perhaps it is, but I like it pretty well.
Another option we sometimes tap is Café 28, which used to be a very hip spot for breakfast ten years ago, but which was almost desolate last time we tried it. The food was fine (not revolutionary) -- but the trend has passed them by, so it was again easy for a pretty large group to just show up and settle in for a congenial meal.
I rather liked Over Easy the one time I went, but it was on Good Friday so less crowded than typical on weekends.
The Golden Nugget on Lawrence has suprisingly high quality diner fare for its type. Not going to win awards, but it's prepared well. It is a bit tidier than the Golden Apple, but perhaps still outside your "scale" window.
