Siris Brew BBQ and Cigars next to Vedge Cafe on the 200 block of North Main has had a long gestation but really will open this winter, promises Geoff Schwartz, marketing manager of Kosch Dining Solutions.

Siris–pronounced like “cirrus” clouds–is “the Mesopotamian goddess of beer,” says Ian Gray, longtime friend and spokesperson for the Kouza family, who was there brokering the introduction to Kosch. The Kouzas have long owned the Main Street Party Store, but their growing investment in the block had also landed them with three restaurants, and over the summer they finally called in the cavalry, aka Kosch Dining Solutions.

Kosch is large, employing as many as 600 people depending on the season (many of its restaurants are in resort areas up north), but it’s a family business. When the Kouzas saw an article about Kosch in Crain’s Detroit Business over the summer, they liked what they read. The two family businesses quickly formed a partnership to get Siris open–and also to revamp and steer Sabor Latino and The Heidelberg back into the black.

Even before Siris opens, Sabor Latino will become Agave Tequila Bar–sometime in January, says Jason Hilliard, Kosch’s VP of sales and operations. The Kouzas quietly took ownership of Sabor in 2011 when they bought the building. Sabor’s owner Marco Wong Baez wanted to close the restaurant, but the Kouzas wanted to keep it going and retained Marco for a year or so as a consultant to keep some continuity. (“I’d wondered why I’d only seen Anglos lately,” said one regular customer drily.) At press time, Kosch didn’t have a menu in place for the new iteration, but Hilliard emphasized that it would continue to be a full-service restaurant, open for lunch and dinner, though the tequila is obviously about to get a significant upgrade.

Siris will be the next on the docket, as soon as Agave is up and running. And finally, Schwartz says, the Heidelberg restaurant (on the main floor) will begin remodeling later this spring. “We’re taking out partitions, putting in big long tables and benches, like an old German beer hall,” as well as a new menu. The food will not be like old beer hall food–it will be “neue Deutsche,” all the rage in Europe. Several restaurants in Germany now have three Michelin stars, and you don’t get those for a plate of brats and spaetzle.
