A Noodles restaurant is under construction near Jack's Alley downtown.
It will occupy space between Panera's and Applebee's near the corner of Fourth and Market.
Workmen are currently tearing out the front and interior from an old one-story brick building that formerly housed several bars.
Four Noodles restaurants are planned in the Chattanooga area, including units in Cleveland, East Brainerd and Hixson.
The chain features "the best dishes from Asia, the Mediterranean and America - prepared to your liking, the Noodles way.
Japanese Pan Noodles, Wisconsin Mac & Cheese,
something healthy or something indulgent - the world's best food is just inside our doors."
The food, including pastas, salads, soups or sandwiches, is prepared quickly. Prices average $7, officials said.
Units in the chain are mainly in the Northeast and Midwest.
