We were just there in Dec. It is a really nice resort. Our plane was delayed on our arrival day, so we didn't end up getting in as early as we hoped and grabbed dinner from the QS at OKW. We had burgers. We were on the dining plan and honestly, I wouldn't waste a QS credit on it unless you were in a situation like ours. Like PP said, I would go to DTD. Earl of Sandwich is good and WPE is super too! Our friends ate at Olivia's and they liked it.
We ended up in building 62. It is an elevator bldg, which was nice b/c w/ our friends, we were travelling w/ 4 kids. I thought this building was perfect. We were right across from the HH and could get off at the first bus stop on our way back from the parks, which was a big plus w/ tired kids.
I walked the entire resort and didn't think any of the buildings were an unmanageable walk from the HH, but take a look at a resort map before requesting anything b/c some of the areas are a further walk from a bus stop than others.
Have fun and enjoy OKW. It is a great resort!
