Toothsome is the best, for sure. Keep in mind that all the current restaurants in park, including QS, were all pre-Comcast. Only food in parks post Comcast are HP, which are the best QS in Orlando. So I have high hopes for whatever they put in KidZone, regardless of IP.
As for the other Universal exclusives- Antojitos is very good. Vivo is “eh”. And Toothsome is the highlight, for sure.
I still always eat at both Finnegans and Confisco- because I can get a table service meal for the price of a quick service. So when you look at it that way, they’re pretty solid. I used to be able to do that at the Plaza, but even that is now priced well beyond QS. Yak & Yeti with shared meals is my last “cheaper” hold out at WDW. And that’s not even Disney, it’s Landry’s.
