Daniel Landes, who founded the popular, 20-year-old vegan restaurant Watercourse Foods before selling it to the mother-and-daughter team of Jennifer Byers and Lauren Roberts, is also selling City O’ City, his last remaining Denver restaurant, to the pair. “We are honored to be given the opportunity to build on the history and tradition that Dan Landes began two decades ago,” said Roberts, now the vice president of Watercourse, City O’ City and the latter’s bakery, Make Believe, via email Wednesday. “We believe there is so much more to these businesses beyond excellent food and authentic service,” she said.
