But there's what, 13?, massive TSRs* competing to get those guests to have dinner. Plus QSRs. And the only way to get guests there is to kick them out of the park by 7 pm, which cuts in-park spending. No one "restaurant-hops." The dinner crowd at CityWalk is largely a zero-sum game, because Universal's former parking policy keeps so many non-park guests away. And they all leave at once, resulting in a massive guest-discouraging line at 7:05, but no one come 9:00.
It again comes down to Business 101. Who is the target market? How large is that market? Will this serve their needs? What is the competition? Antojitos, standing alone, is a really cool restaurant. But who is going to eat there? How do you get them to go there? Why will they choose Antojitos over Rocco's Tacos? It's the difference between looking at pictures online and realizing nothing exists in a vaccuum.
I hate to use the analogy, because TWDC loves it but doesn't get it, but CityWalk and to a large extent Disney Springs are Red Ocean. Adding venues to cannabalize existing ones. I-Drive right now is Blue(r) Ocean, targeting a market that hasn't been adequately served the past 5 years.
*[I've heard HRC may be the largest restaurant in North America, certainly the largest in Orlando. The rest besides Emerils are not small.]
