From the Lambert Airport communications office:
The Pasta House is making a comeback at Lambert after a four year hiatus. It's replacing Brews & Blues that closed this week in the lower level of the Main Terminal. The Pasta House was formerly located in Concourse D. The new location will bring patio seating to the Main Terminal once construction is complete in about four months. The Pasta House will be operated by Deli Enterprises, the same great folks who operate the Great American Bagel.
Later this summer, Lambert visitors will see more new restaurants under construction as HMSHost begins work with some exciting new concepts in the West End of the Main Terminal Ticketing Hall.
