We probably won't know for sure until it re-opens on the 10th, but my guess is that it'll use the same (or similar) space it used when it hosted the F! dining packages. So there were still some tables for the Stage Door Cafe, but most of the ones closest to the RBT's entrance were used for the dining location.
I'm looking forward to reading the reviews. I wonder how close the BBQ flavors will be to the Big Thunder BBQ. The photos in the Blog post look kind of similar, but different (e.g., there are black beans in the beans).
