Orange Club is listed as a pool hall at 9 City Rd in Grafton, Auckland. It has a 4.3 rating on Google, and its website address suggests it also runs as a nightclub.
A good pool hall keeps its tables level, its cloth in good condition and its cues straight, because those things matter more to your game than anything else. Where a venue mixes pool with a nightclub, the feel changes through the day, with a quieter game early and a busier, louder crowd later, so check the website for opening times and any entry rules. Tables are usually charged by time or by game, so ask how it works when you arrive. If you are new, say so, since most players are happy to share tips on chalking, bridge hand and cue ball control. Regulars know that early evenings are easier for getting a table and that house cues vary in quality. Bring ID, as venues with a bar will check it.
For anyone in Grafton and central Auckland, Orange Club on City Road is a place to play a game and go out.
