H2NO Chiaia In Napoli

28/08/2025: The food is delicious, but going there to queue is crazy...so slow...absurd...not worth it!

28/08/2025: I've eaten at the Spaccanapoli location several times and have never had any problems. Unfortunately, this wasn't the case at the Vomero location. The wait for the receipt was very long, and the staff was slow both in the kitchen and at the register, as those at the register left to go to the kitchen. After 30 minutes of queuing for the receipt (despite there being about 9-10 people in line before us), we waited another 50 minutes for the sandwiches to be delivered. Priority was given to deliveries from drivers, even though they weren't yet at the restaurant to pick them up, so all the orders they were preparing weren't for people outside the restaurant. We were number 123, and after half an hour, the number of 108 had gone down to 112. Furthermore, the girl who bagged the sandwiches did so insensitively, so much so that the bacon fell out of the sandwich (the bacon we paid for, which also disappointed us, wasn't crispy at all; I had to remove it from the sandwich several times because it was so full of grease that I couldn't even chew it). Despite this, the sandwich was good, although it's been decidedly better on other occasions. I don't know if it was the crowds' fault, but I certainly won't be returning to the Vomero location.
