I have seen it on a site plan for the retail area across from the Hilton. This was in 2004 I think. It was next to the parcel labeled "TGI Friday's". The owner of the land was holding the site plan so it seemed pretty legit to me.
There must have been changes, however...because the plan I saw had a half dozen restaurants kind of clustered around that detention pond / water feature. It may turn out that way in the end, but right now what's on the ground doesn't resemble what I saw. I don't know what happened with the Carrabba's deal and I haven't pryed when I happen to run across the developer now and then.
