Domestic flights are now using a separate entrance in the older part of the terminal. Once you're through security, you get dumped off on the ground floor - at the end of the new terminal building. Arrivals are still into Terminal 1.

The domestic lounge is a bit small, but there's a small hot/cold food buffet and some beverages. It's located right next to all the boarding gates (all of which are bus gates) There's somewhat of a view over the main waiting area of the domestic terminal.
