I was at the ferry building earlier to pick up some orders. It took ages despite pre-orders. The line for Acme was a total joke, I didn't even attempt it.
Good news - go to harvest urban market in SoMa. They have lots of lovely fresh looking Acme bread.
I had a handful of last minute grocery items to colect. I couldn't face fighting my way through Wholefoods or other similar shop. It suddenly dawned on me that I'd seen that new market, and I'd been meaning to try it.
Loads of parking right outside the door, only about 10 customers, helpful staff. A breeze.
If you need a last minute item in a peaceful environment, it might be a good bet.
