It's a huge mall, as expected. As malls go, it's one.
Wife enjoyed it, and I made a game out of counting how many Caribou Coffees there were (over 15). Can catch a bus from there to Indian casino.
As stated, Lego store is cool - my wife left several $100 there, and I learned to repack legos into ziplock bags to reduce volume so as to fit into luggage and carryons.
Downtown Minneapolis is cool - see the sights (stadiums, indoor walkways, Mary Tyler Moore statue, etc...). We were there in fall on Vikings gameday, and it's a fun crowd.
Bar at mall is nice - make sure to have a Grain Belt and a Summit EPA.
This is the Pub. Leave common sense at the door.
