Coffee spot Greenhouse will start slinging espresso-based drinks and gluten-free pastries in Olmos Park Sunday, Jan. 21, according to a Jan. 6 social media post. Co-owners Rico Torres and Diego Galicia — who helm nationally lauded Southtown spot Mixtli Progressive Mexican — have partnered with Mixtli chef de cuisine Alexana Cabrera to take over the space at 223 E. Hildebrand Ave., Suite 101B, which previously housed a short-lived Chick’n Cone eatery.
