Wow Barry, I didn't know you could talk that loud, lol.
Margaritaville is good but very popular. Last saturday evening at 9pm it was an hour wait WITH priority seating. But we've gone at 6pm and were immediately.
Same for Hard Rock cafe: We ate there at 5 pm and were seated right away. Last friday evening, after the mardi gras parade, the line was huge. Luckily we had our Hotel key and an Hard Rock access card and were seated right away.
We went to Pastamore (also at Citywalk) and there was no wait. The food was pretty good and prices reasonable.
On average I think you can expect better food in IOA than Universal. In Universal, Richter's has large burgers (including a veggie burger), fruit cups and a nice patio out back.
In IOA, confisco's has good food but a limited menu right now.
Enchanted Oak Tavern has things like Turkey legs (dry) with lots of carbs on the side, corn on the cob, corn muffins, fries. The theming is interesting, check it out.
If you enjoy italian food try Mama Della's at Portofino. Just take the boat over from the Citywalk dock. It's pricier than your average dinner but the food and service are excellent!! It can also be busy on the weekends so you might want to call and make a res.
