I work just across the street from Newk's and love, love, love grabbing lunch from here. It's always very busy at lunch, so I order my food online from their website and go to the express register in the back by the soda machine to pick it up and leave. I'm in and out in less than 3 minutes. I really can't recommend standing in line and eating in the restaurant during lunch - it's just a madhouse.
The food - get the soups. My favorites are the tomato basil bisque, the corn and crab chowder and the lobster bisque. When you get a soup, you have the option of ordering grilled bread - do it, so worth it! I also really like their salads - they are always crisp and fresh and generous with the toppings. There's an "extras" bar by the cash register - grab a couple of packaged breadsticks to go. For sandwiches, I like the seared ahi tuna and the grilled steak sandwiches. I usually will order a half sandwich and a half salad (on the days I don't get the soup).
