Yes, they have a menu that you can order off. I can't tell you what was on it because we had the buffet.....but there was a couple next to us pouring over the menu for quite some time (which is why I noticed...the poor waitress came 3 times asking if they were ready).
You might call the Swan directly and ask them if they have a copy of the menu that they could fax to you to peruse.
The buffet was really wonderful, by the way. Not at all your typical buffet, everything kinda tastes the same. The made-to-order pasta was excellent.
