If you’re dining out on a weeknight, you could catch some deep discounts on wine. A growing number of restaurants designate a day — sometimes more than one — for up to 50% off bottles of wine. A few offer discounts on wines by the glass. The promotions aren’t always posted on the restaurants’ websites, making it something of an insider’s deal. Here are some that we’ve discovered:
