Labor Day Weekend, Saturday, August 30th, 2014, through Monday, September 1st, you can eat for free at IKEA’s restaurant if you buy furniture. Here’s how it works. First, dine. Ask for a coupon. Hold onto your restaurant receipt and the coupon. Then shop. If you spend over $100 (before tax) on home furnishings, hand over your receipt and coupon and the amount of your meal will be deducted from your home furnishings purchase.
