Definitely CiCi's

. There are tons of buy one buffet, get one free coupons available at hotels and businesses along I-Drive (or you can print yourself from the I-Drive website). Regular price for the buffet is $5.99 per person, and that includes soup, salad, pasta, pizza, desserts and water. Considering the sheer volume my boys can eat, this was an AMAZING value (particularly when one of us was no charge....with three sodas, our meal totalled just over $17 taxes in).
Another awesome value from our last vacation was TGI Fridays. They had a deal where you got a full sized appetizer, a full sized entree, and a dessert for $12.99. I had a HUGE plate of mozzarella sticks, a monstrous bowl of pasta, and the best peanut butter chocolate pie I've ever eaten. DH upgraded his meal to a steak platter for an additional $4, and added a beer. DS had a similar meal to mine. For three full sized appetizers, one chicken entree, one pasta entree, a steak entree, my pb choco pie, a slice of vanilla cheesecake, an oreo cookie ice cream dessert thingie, DH's beer, taxes and tip, it came to $65. And the food quality was fantastic. We can't even come close to value like that at our Canadian chains.
