A huge industrial kitchen behind the ballrooms can serve up to 3,000 people. Officials say the sheer size of the expansion will result in a more diverse clientele, opening the door for large-scale events like concerts, weddings and theatrical productions. The addition, dubbed Mystic Lake Center, will include a 70,000-square-foot event center with several breakout meeting rooms and executive spaces to help attract lucrative convention business. 'The only thing that would prevent it being done on time is an act of God.' 'There is no wiggle room,' said Tom Polusny, Mystic Lake Casino Hotel's executive VP of operations. It's on track for an early January opening and already is fully booked for the Feb. The Shakopee Mdewakanton Sioux Community (SMSC), which owns and operates Mystic Lake and nearby Little Six Casino, said growing demand was the catalyst for the expansion.
