Everyone thought the food was excellent. Elizabethan has a very wide range of options for their buffet menus, which we liked.
I do have one suggestion if you are getting the midnight lunch: find out where the packaging is (if this is even provided) before the serving staff leaves, since we had to improvise packaging to take leftovers home.
A string quartet fit perfectly with our ceremony venue (Convocation Hall at the UofA). Our contact with Stringbeans was friendly and helpful. They even did a custom arrangement of a particular song we wanted for the recessional (I Believe in a Thing Called Love by the Darkness) and it turned out great!
