OK, so we wound up not having the dinner this weekend. Due to added guests and complications, we wound up at Bub's Barbeque in Sunderland. About a mile from campus, and not really chow-worthy or at all crowded on graduation day: that's gotta tell you something! The sandwishes were sliced meat in what tasted like Kraft sauce, but it could have been worse: at least it wasn't packed and/or far away.
What we are is completely determined to have dinner at TJ Buckley's: the people were so nice when we were working out reservations/times - I can't wait. Probably will get there in a month, and will report to the Board. Thank you all for your suggestions.
