I really enjoy Jason's Deli. It is by far my favorite salad bar to visit. They have enough of the old salad bar standby's that you always want, with an eclectic mix of other items to keep it interesting, like roasted red pepper hummus, gingerbread muffins, and large garlic bread croutons.
I really don't like the way the bar is set up, though. You have to walk down both sides to get at all the different options. I suppose it saves them space, but it is annoying, and I'd imagine frustrating when busy.
They have great soups and sandwiches too. I've never been unhappy with my choices here.
