The Mall of America is a lot of things – biggest shopping center in the nation, one of the busiest tourist destinations in the country, home of the SpongeBob roller coaster – but a place of Zen, it is not. Or at least it wasn’t. Powerhouse yoga retailer Lululemon opens at MOA on Friday, Oct. 15 and will show off its sculpted booty in the mall rotunda Sunday for an 8 am. yoga session led by phillyd’s Inspirational Hip Hop Yoga. Imagine how well equipped you’ll be to handle the line at Nordstrom Rack after that.
