Frankly, I'm having my doubts. The opening of downtown's first supermarket in more than 50 years has been delayed yet again, according to the Downtown News. Now they're looking at the end of July. But hey, it's already three years late so what's another few weeks? The 50,000-square-foot store on Ninth between Hope and Flower streets will anchor the Market Lofts, which is just a few blocks from what will be the L.A. Live complex. Not having a downtown supermarket has been a nagging embarrassment among boosters trying to draw residents.
