Austin-based Halcyon Coffeebar is expanding to the Mueller area this spring. Construction began at what will be the flagship location at 1905 Aldrich St., Austin, in January. Restaurant group Texas Zebo is currently crowdfunding to help pay for the new Halcyon and for Stella Public House, a pizza restaurant which will also open in the area this spring. Texas Zebo opened the first Halcyon Coffee+Bar+Lounge in Austin’s warehouse district in 2001. www.halcyoncoffeebar.com
