Fresh Kitchen is probably the healthiest place that isn't Subway within walking distance of my Barlow offices.
They have an incredible array of fresh soups, salads, pre-packaged lunch plates (pasta, chicken, etc.) and made-to-order sandwiches and lunches.
It is a little on the expensive side for some items but it is well worth the money spent. I've heard Fresh Kitchen's owner used to be involved with Sunterra, so he comes with great knowledge and experience.
As someone now living a sugar-free (as much as possible) and clean-eating lifetstyle, I am confident in Fresh Kitchen as an alternative if I don't have time to prepare my meals for a day.
