Ever since the implosion of erstwhile darling Umami Burger a while ago, the space at 235 Main St in Venice has sat empty. That’s about to change. A banner over the front of it lets us know that LA Urban Fitness is set to open a cafe and nutritional supplement shop. LA Urban Fitness used to occupy the nearby space at 3015 Main St in Santa Monica, just a few blocks away. If they follow their old model, we can expect a menu of smoothies, cold-pressed juices, Groundwork coffee, and snacks.
