One of the notable things about the syndicate is that they offer incredibly expensive Ribbons, which act mostly as signs of status rather than merit. The counter is located on the first floor, just beyond the entry. The lady there will offer each Ribbon one at a time according to the price; the Gorgeous Ribbon first, then the Royal Ribbon, and finally the Gorgeous Royal Ribbon.
The syndicate also features a spa on the top floor. A visit to this spa, like grooming in the earlier games, makes a Pokémon more friendly. They can only accept five Syndicate members a day and a Trainer who receives a massage may not receive another until the next day. Unlike masseuses, the spa attendants are willing to operate on an Egg; this will increase its friendship after it hatches.
Hope I helped!
