Sammy's is a nice place to grab lunch while on campus. They have relatively healthy choices, which is really nice. I would recommend the grilled veggie pita. Healthy and hearty for $5.25 (plus tax). Today I ate the grilled spicy tofu pita, which I would not recommend. I found it a bit bland.
The have a selection of juices and smoothies, as well as fresh salads and baked goods. Overall, it's just a nice place to stop and grab a bit to eat. It's not totally cheap, but it could be more pricey.
I find the staff who serve the food are quite friendly, although the woman at the cash seemed a bit sour. Then again I was during the lunch rush, so maybe she was just tired?
A veggie sandwich and a side salad (no drink) came to $8.42.
