Harvest Market is good, the one SOMA is better than the one in the Castro on Market.
My last Delissio visit I found the polenta and Mac n Cheese dishes were too oily and the chicken tasted weird and too fatty, I ended throwing in the trash.
I think it depends on which Whole Foods I have had better prepared items at the SOMA and the Calif. locations.
There are several places in the Ferry Plaza that have prepared take out, Boulette's Larder is one of a few.
In San Anselmo you cannot beat Comforts Restaurant and Deli.
Genova Delicatessen in Oakland - I use to keep a couple of their lasagnas in my freezer to have on hand, good soups.
Bi-Rite Market- has some good items
Bryans Market on California has wonderful crab cakes easy and nice to have with a salad.
Cafe Madeleine- if you work downtown try their chicken pot pies and a few salads are good.
Delissio (2 branches, one on market near Valencia, one on Broderic at Oak) has wonderful prepared food. It's all pre-cooked and held somewhat warm. I'm sure if you have a large event you can plan ahead with them and they could prepare large batches, but otherwise to feed up to 8 you could just grab that much food from them.
I like Delissio's food much better than Whole Foods, Mollie Stone, etc. for prepared vegetables, meats, soups and the like. Delissio also has fantastic cakes, cupcakes, and other desserts that WF or Mollie Stone can't touch with a ten foot pole.
