If you hang around in the arrivals area for long enough, I'm sure some people will turn up and invite you for a chat....
Once you're off the plane, you'll be directed to either immigration, or transfer security, depending on what signs you follow. After immigration is baggage claim, then customs, but unlike in the states you don't need to fill out forms or queue up for customs, just walk through + stop if asked. There are toilets in the arrivals side, but that's about it. All other services are landside.
