Minneapolis coupon books?

my family and i are travelling to minneapolis the 16th-20th of march. I have already purchased the nick universe wristbands online..so i was wondering which coupon book is better...the MOA coupon book. or the twin city happenings/entertainment book.. i have no idea what type of coupons are in the moa book. the twin city one i found out what was in it online.. i have three small children..any insight on eating cheaply would be appreciated..thank you so much!! we do plan on spending a lot of time at MOA
