Post Oak Hall owner Ellen Daehnick was born and raised in Houston, Texas, and has fond food memories of her years there -- and she wants to share those food memories with you. She's been making caramels and other sweets under the Helliemae's name for the past few years, and launched Post Oak Hall next door to her candy kitchen in late 2016. Unique in Denver are her Houston-style po' boys, but if you order one, forget the shrimp and oyster-stuffed sandwiches of Louisiana; the Houston version boasts ham, salami, provolone, dill pickles and chow-chow on a French baguette. Daehnick also serves up kolaches and other treats from her home town to the northwest suburbs. Go early: The hours are limited at this tiny takeout-only joint.
