I LOVE this promo from Maggiano's Little Italy (which is super-tasty, by the way!). Dine in at any Maggiano's and order one of their Classic Pasta dishes for $12.95, and they'll give you a SECOND Classic Pasta dish to take home for FREE. This is available all the time - no coupon necessary. There are NINE Classic Pastas to choose from.
Sign up for their e-club, and they'll send you a coupon for $10 off your next visit!
