When we got there we were served and seated with a friendly waitress who was more than helpful. We ended up ordering their signature dessert churros and kids churros with chocolate even though there was a mile long list of endless choices. It did however take a while for these dishes to come out to the point the children were getting restless and they weren't piping hot straight out of the frier like market churos. It's probably to be expected though given the serving environment and the fact these things go cold quickly.
In the end I would go back because it is child friendly and the staff were more than lovely even joking with me when I took photos. To me if it's got a good vibe going on where people like being at their job and are happy to give good customer service I'm not going to be over zealously picky about judging the food. If you keep in mind it is a mass production chain store, I think it's pretty satisfying. Hopefully the slow service gets sorted out in the future as this is the kind of place your kids will reminisce on being taken to once they reach adulthood.
