Just because you're going to sit around and eat too much it's no excuse to stop sketching. You don't even have to leave the table or stop participating in the conversation—just push your plate aside to make room for your sketchbook. If all the food has been eaten, you can draw the glasses, forks and crumpled napkins. See what people sketched in 2013 here (http://www.meetup.com/SF-Sketchers/photos/18805042/) and 2012 here (http://www.meetup.com/SF-Sketchers/photos/11865262/).
If you RSVP "Yes" for this meetup, that means you're planning to do at least one food sketch and post it on the meetup site.
