I've eaten here a few times, and here's my Mrs. Winston's Green Grocery review. It's a great place for a causal and inexpensive bite.
The salad bar spread is extensive and very vegetarian and vegan friendly. Lots of different flavored tofu salads (curry tofu, kong pao tofu, spicy peanut tofu, etc.), a couple mock meat salad choices, many sprout choices (broccoli, alfalfa, clover, pea, etc.), greens dressings, and lots more. I like to fill my plate with all the goodies.
For two people both with a large plate each from the salad bar, we paid $20. Everything was yummy.
