Actually, your choices from lunch at CityWalk are limited since many of the clubs and restaurants don't open until until 4 p.m. or later. That still leaves you with some great choices: Pastamore, Hard Rock Cafe, NBA City, Nascar Sports Grill, and Margaritaville and any of them would be a good bet. Personally, I think Margaritaville is the most fun followed closely by Hard Rock. Pastamore has a good menu but it's pretty non-descript so if "atmosphere" is part of the equation it would be my last choice.
