Not sure what's going on with this restaurant. I was visiting Lafayette today and tried to check out Peaceful Greens. Their website was down yesterday and today. I went by in person today and there's a sign on the front door that says they are closed all week. Hope they are up and running again soon.
Parking was difficult but not impossible. Once you find a spot, there's no charge (no parking meters) so that is nice. Be careful with all the one-way streets in this area.
If you go to Peaceful Greens and it's closed, there is another all-vegetarian restaurant just up the street called Copper Dog at 660 Main St.
