Some local restaurants will support National Lasagna Day – that’s right, there is such a thing – today (July 29) by offering special discounts on the layered dish. Offers are only available to dine-in customers. All Brio and Bravo locations are offering half-price discounts; lunch orders are $7.63 (regularly $15.25) and dinners are $8.48 ($16.95). At the Spaghetti Warehouse on the West Side, a serving of lasagna, salad and bread is selling for $4.99 with a coupon, still available through Facebook. Buca di Beppo is giving away a lunch-size lasagna portion with any small or large pasta or entrée, most of which range in price from $10.45 to $33.95. (By the way, a small portion feeds two to three people, and a large feeds four to six, an employee at the Arena District store said.)
