Not being a meat eater it is hard to find a good sandwich place, but Sacks Impressionist (Veggie) is one of my favorites. It comes fully loaded and with lots of options. And if i'm feeling a little fishy, both their tuna salad and tuna sandwich are other go to items. I am usually pretty picky about my tuna, but Sacks is fresh and not smothered in mayonnaise.
This is a great spot to call in a pick up lunch on the go.
