I have an 8 year old boy. He'll be 9 in December.
He definitely gets food for himself, though he'd be happy to let me do it for him if I hadn't started having him do it for himself when he was 6 or so!
He has to pull over a chair to get glasses out of the cabinets, but he can definitely toast his own bread, make his own sandwich, and heat stuff up in the microwave. He can turn on the stove but, to my knowledge, he's never actually cooked something himself. We do make cookies together.
He gets himself ready for bed (brushes teeth without supervision, gets undressed, gets into bed), but we always read him a story and tuck him in.
He kind of cleans up after himself. He likes his room to be neat, so he'll clean it himself and sometimes he just decides to vacuum or clean up other areas of the house (*LOTS* of positive reinforcement for this behavior!). But a lot of the time I have to remind him to take his glasses and plates to the kitchen, rinse them off, etc, unpack his backpack, and generally pick up his stuff.
He can and will walk himself places -- up to about five/six blocks. We live in Europe and our neighborhood is safe and relatively car free, so most kids play outside pretty unsupervised. We're pretty free-range, in general. However, it took some encouragement to get him to where he'd feel comfortable walking and playing on his own. He's naturally a bit hesitant, so we've had to actively encourage independence.
