Have gone to Asadero Cien twice this visit, mainly because I love grilled octopus. The first time was good, solid service, and good food. Maybe not spectacular, but very good. The second time was kind of a disaster ... the octopus was still pretty darn good, but the service was terrible. The waiter spoke so fast that two native Spanish speakers (plus me) had to ask three times for him to re-say things. When we requested non-alc beer, he said that they did not have any... the manager later said that they will happily run across the street to get some, and for that reason they have it on the menu. Getting the official receipts ("facturas") took a solid hour afterward... big waste of time.In sum, I have not tried the red meat here. The octopus is the best in the city, and is quite fresh and tasty. That is why I have eaten here twice this visit. The other dishes are good too ... queso asadero served with grilled nopal is excellent. The desserts were quite respectable. The food is thus good, if not spectacular and mind-blowing.The management needs to work hard on improving the service, however, from top to bottom...
