Long lines? Yes. Is it worth it? Definitely. I usually order from Seamless Web to avoid the long lines, but Just Salad never fails to deliver. Except once, when I inadvertently typed in the wrong office suite and sent them a free pesto chicken salad. Just Salad is not cheap, but I would much rather pay a premium for quality ingredients and veggies, than pay less for a less healthy alternative. I would definitely try their Roasted Red Pepper Vinaigrette as well. Also, i'll let you in on a little secret: They just started serving pinkberry-esque frozen yogurt. I have heard rave reviews of it, but have not yet gotten in there to try it. Will hopefully have an update soon.
Pros: fresh, fresh, fresh, many choices
Cons: long lines at peak times
