Bruegger's Bagels Bakery is another restaurant where, after you order it, your food is prepared in front of you.
They have several varieties on sandwiches that are served on bagel "buns." There are many varieties of fresh bagels to choose from.
I had a "Radishy Roast Beef" (horseradish sauce, not sliced radishes) on a "Rosemary Olive Oil" bagel. It was VERY tasty. The sandwiches were all priced at about $5 each. They actually weren't big enough to justify the price, but mine was good enough that I didn't regret spending the money.
