Hello, again Gang! Lunch with an Imagineer is another thumbs up! We highly recommend it.
There was a mix up by the CM at booking, so we almost did not get to have this experience this trip. (We thought the reservation was for Fri but they called from HBD on Wed asking where we were). Fri's lunch was full, but the CM, Sonia, went above and beyond and called 2 managers and the imagineer himself to approve adding 2 more people. So we did get to go. 
(This is why we like to spend our vacation time and $$ at WDW).
Ordinarily there are 8 guests plus the imagineer, but in our case 10. We had a brief "tour" of the HBD (just showing photos around the restaurant and giving a little history). We also received red nametags that look similar to CM tags. Then we went to a small private room, took our seats and met our imagineer, Dan. He is currently working on the refurb of Space Mountain and working on the DVC in Hawaii. (This did contribute to our renewed interest in DVC, as several others at the table were members and raved about it).
Our waiter was Moses and he was excellent. There were 11 of us eating and we never even thought of anything we needed...it just showed up. Drink refills, soup spoon, whatever you needed was there before you even realized you needed it.
Food was excellent. We are fans of HBD (I know there are mixed opinions) and even we were pleasantly surprised. There was soup, the famous Cobb salad, your choice from 3 entrees and your choice from 2 desserts. I had grouper, DH had steak and others had the noodle bowl. Everyone was very happy with the food.
The discussion was varied. The imagineer really leaves it open to the group's questions, so some folks asked good ones and some, IMO, were kind of silly or related more to marketing than imagineering. But everyone chimed in and there was conversation amongst the group as well as just with Dan. Of course, he cannot tell us anything that has not been announced or speculate on any rumors, but it was fun to ask how the creative process works and how ideas become attractions.
Afterwards, we were given the menus we'd used in addition to a photo of the group signed by Dan. We were promised a souvenir plate to be mailed home. Usually they give them to guests at the lunch, but did not have enough (maybe because we were 10?) I actually prefer having it sent, then don't need to worry about keeping it in 1 piece on the flight home! Haven't received it yet (only home a week).
We really enjoyed the experience and would recommend it. It was fun and different. Gives us another response to "You're going to Disney again? 
And think, free disney passes!!
