When I dressed for work this morning, I should have worn black, because the River Room, a St. Paul tradition since 1947, served its last popover today.
The restaurant, what this diner has long considered to be the main attraction of the St. Paul branch of the Store Formerly Known as Dayton's, started across Wabasha Street (that's a 1940s postcard depicting the restaurant, above, from the Minnesota Historical Society). The restaurant's name was a nod to the large-scale murals of the Mississippi River that adorned its original home inside Schuneman's, one of several old-line department stores (including the Golden Rule and Emporium) that no longer exist.
As a Minneapolis-side-of-the-river kid, I was unfamilar with Schuneman's, and its evolution into Dayton's, so I did a little digging.

Here's the store as it appeared in 1920 in a Minnesota Historical Society photo (that's the Hamm Building on the far left). By 1963, when the store was known as Dayton's-Schuneman's, it moved across the street into the present-day Macy's. The River Room made the move, too, where -- until today, anyway -- it has been the Saintly City's answer to the Oak Grill, the beloved grande dame holding court on the 12th floor of Dayton's downtown Minneapolis store. Coincidentally, the Oak Grill also opened in 1947, in a burst of post-war expansion.

Believe it or not, Dayton's St. Paul store was the height of retail modernity when it opened. Here's the Cedar-and-7th corner of the store, shortly after its 1963 debut, in a Star Tribune file photo.

It's the work of Austrian architect Victor Gruen, and, from the looks of it, it's not completely out of bounds to wonder if he drew inspiration for the store's design from a Dayton's hat box (I can't be the only one who sees the separated-at-birth resemblance). If that name sounds familiar, it's because Gruen was the mastermind behind Southdale, the Dayton department store dynasty's retail breakthrough. The Edina complex opened in 1956 as the the nation's first fully enclosed shopping mall, a prototype that was copied from coast to coast.

Southdale was an instantaneous success: "A pleasure-dome with parking," hailed Time magazine, while Architectural Record weighed in by saying, "in Minneapolis, it is the downtown that appears pokey and provincial in contrast with Southdale's metropolitan character."
Following his Southdale triumph, Gruen (pictured, above -- center -- in the garden court at Southdale, still under construction, in a 1956 Star Tribune file image) was hired by a group of St. Paul business leaders to remake the city's aging retail district into a shopper-friendly zone. His first suggestion: re-think what was then the planned I-94 freeway. He urged the state's highway department to place the freeway north of the State Capitol, to preserve the connection between the capitol complex and the city's business core. His proposal never went anywhere, and the freeway's city-splitting route remains one of the Twin Cities' great urban design disasters.
