I *think* that the chair covers are included (I may be wrong though) and that you have to pay extra for the chair bows. I think the only colours they have there are purple, gold and silver. That does not work for us so we will be bringing our own.
As for the reception dinner being at the Steak House, apparantly it is the nicest and the best and the most sought after so once I found that out I emailed Erika and booked it right away since it can get reserved way in advance.
