Once there, speak with Alisaie at (X:21.1, Y:21.9).

He will issue a quest titled 'Primal Awakening' and send you to Wineport in Eastern La Noscea. Once you've met all the requirements, head to the Waking Sands and meet Urianger at (X:6, Y:4). You'll also need to have attained Level 50, but chances are pretty good that if you've completed the requisite quests you're already there. Once you've completed The Bowl of Embers (Hard), The Howling Eye (Hard), and The Navel (Hard) by defeating Ifrit, Garuda, and Titan respectively, The Binding Coil of Bahamut will unlock.

Before you can even attempt The Binding Coil of Bahamut, you'll have to finish some top-level quests that pit you against classic Final Fantasy foes.
