One big thing about Metro Manila. It’s called Metro Manila.
Manila is the oldest part of Metro Manila. Here’s where you’ll find Intramuros.
Makati is the most posh part of Metro Manila. This is the Central Business District.
Taguig used to be non-entity, but ever since Serendra and High Street opened there it’s kinda been another place to be. Besides it’s beside Makati.
Quezon City has Cubao in it.
San Juan has Greenhills in it.
All these places I mentioned are either cities or municipalities in the greater area called Metro Manila.
