I would vote no on this one also - until after a meet and seeing if there is a connection, we wouldn't even consider that - it would be a Thanks, but no thanks.
I can understand him not wanting to commit to dinner and be stood up - it's not like a couple who can have a great time together - he's eating alone.
As an alternative, I would suggest drinks at a local place or as mentioned above Starbucks
(not our favorite coffee), then at least he can have a cup of coffee and leave.
Good Luck!
