I know appropriate meeting and food locations are not easy to find, and you are doing a great job.
However, I though I would add one more to your list or potential candidates.
320 North Peters Road Knoxville, TN
We had an American Nuclear Society (ANS) meeting there last month, and I realized they have a number of "banquet rooms" in the back where we had our meeting.
I checked the website, and there is no room charge, but there is a $19 per person minimum. Seems like we have been meeting this minimum during recent events. Also, the bill is on one check. For ANS meetings, we have a fixed price that is collected when one enters, and then the organziation pays the check.
This is a relatively convenient location, at Peters Road and Cedar Bluff. And the banquet room provides nice separation from the rest of the patrons. Perhaps you have already investigated Peerless, but this name did not have a strong name recognition with me. They have been in Johnson City for 75 years, and opened at this location in approximately 2006. So, as you can see, I don't keep exactly current on "new" restaurant openings, as Peerless has been at this location for at least 7 years.
See ya'll at Red Lobster tonight and looking forward to the Dream Run selection.
