Yes...there are three restaurants in both parks that accept the meal deal. Of the three IOA restaurants, I would recommend Comic Strip Cafe over the other two...although The Burger Digs is good when you hit it right. Comic Strip Cafe has lots of choices and The Burger Digs will give you lots of topping choices for the burgers. It's a great deal when you are taking teens who eat a lot.
Comic Strip Cafe is great, has a lot to choose from. Burger Digs has great burgers and FRIED FISH!!! And a lot of toppings like you said for burgers. I usually make a side salad here lol.
I get the meal deal 80% of the time. I think it's a great deal. You can eat salads, burgers, hot dogs, Chinese food, fruit, pizza, pasta, deserts, chicken, chicken tenders, fries, onion rings, and more! Definitely a great variety for everyone.
Example: The last time I got it I ordered 2 ceasar salads with grilled chicken (about $8 each), Mediterranean salad or something (about $8 each), rotisserie chicken with corn on the cob and corn slaw (about $9), Chicken tenders with onion rings (about $9). So that day cost me $22 for the meal deal and would of been $42! Not including the deserts that are included. It really depends how much you eat. If you plan on being at the park the whole day and are going to have at least 2 plates of food, I think it's worth it.
Keep in mind, if you like soda, you can add unlimited soda for about $10. This is just the first time. Once you have that cup, you can bring it back whenever you'd like and as long as you get the meal deal, you'll receive free refills. I bring water bottles to the park, but it's a great option for soda drinkers!
