Recently found this place and am really enjoying it as a lunch option. It's on 2nd between Mission & Market. You get tossed-to-order salads and call out what you want tossed in from a wide variety of add-ons (veggies, meats and cheeses). Six or so dressings to choose from. The small (half) is plenty of food (for me at least), and you can pair it with a half sandwich (pre-made) or soup for $7.50. This is a great value I think for the area. Soups today included a carrot ginger (very tasty) and broccoli cheese (they had run out of this by 12:30, and on a holiday no less).
I'm looking forward to future salad-and-soup combos to come. Website below.
