Imho, mcdonalds is the best, really quick and very accurate. ..unlike the mcdonalds near my house. Should you opt for that there's a 15% off coupon here which lowers the price in line with regular mcdonalds

I scoffed at the idea of going to mcdonalds last time but it was so closer to the Carousel Inn and so easy that we went a bunch of times and i wish i had printed these coupons, but they did give you a coupon for two egg mcmuffins for the price of one if you filed out a survey online, which i did use since we went there like 5 times in 3 days
