Thanks again, for all the suggestions. Owing to geographical and logistical parameters, and the fact that it had been on my "to try" list for a while, we ended up at Ten Mile House for our lunch today.
As was mentioned above, the space was conversation-friendly, comfortable and pleasant. The north-facing windows provided a ton of beautiful, indirect daylight. Our server was friendly/feisty and ultra-efficient. I ordered the Mile High Club, which was a solid and ample take . . .
Mile High Club @ Ten Mile House -
house smoked turkey, bacon, avocado, lettuce, tomato, bacon-shallot mayo, whole wheat toastI thought the sandwich was very good. I appreciated the restrained smoke on the turkey, the fancy mayo and the freshness of all the ingredients. All in all, it was a very nicely conceived and composed sandwich. Fries were very crispy but insanely salty. Because of how well they were cooked, I wanted to eat more of them but there was so much salt on them, doing so would have been painful.
In the end, the food was plenty good enough and the space was just about perfect for our meeting. There were moments during which I was grateful it was so quiet, as one member of our party was talking pretty softly. In a louder room, I might have had trouble hearing him. And, not surprisingly, he was an interesting and experienced person with quite a bit of wisdom to share. I'm glad I didn't miss any of it.

Thanks again, for the fine suggestions.
