Kiss for Free Food at Qdoba on Valentine's Day

Customers at the restaurant in the Arnold Commons can get free food on Tuesday, if they don't mind a little PDA.

The promo is called Bogo For a Kiss.

The nationwide chain is bringing back a Valentine's Day promotion that, according to spokeswoman Ashley Cohen, tens of thousands of customers took advantage of in 2011.

Anyone who buys an entree can get another for free—once they kiss a fellow customer at the cash register. It doesn't matter (to Qdoba) who it is.

No coupon is necessary. The promotion is happening nationwide, though in Wisconsin, inexplicably, the second entree is 50 percent off, not free.

An employee at the Qdoba in the Arnold Commons Shopping Center confirmed that it is taking part in the promotion. It's open from 10:30 a.m. to 10 p.m., on Valentine's Day.
