For those who like their lunch with a sweet treat, Dairy Queen just launched its 5 Buck Lunch. The lunch deal is available daily from 11 a.m. to 4 p.m. at participating locations. Customers have their choice of a ¼ lb. GrillBurger with cheese, 3-piece chicken strip or a chili cheese dog — all served with fries, a beverage and small sundae for just $5. For a buck more, diners can upgrade the sundae to a small Blizzard. The offer is for a limited time.
