There was a special at Sustain a week or so ago, "lamb belly" that was served over a bed of ramps. Not sure where they're getting them from but hopefully they'll appear on the menu when they're available.
Thanks Charlie...I think I'd like to order everything on that page! I wouldn't really call it an obsession though, more of an intrigue. It's probably the fact that they are just out of reach that makes me so interested.
