The King's Arms is a huge stylish pub at the top of Whiteladies Road (opposite the Esso Garage) There's plenty of free parking on W'ladies Road or close to the Downs. As for public transport, you can plan your journey here: http://www.firstgroup.com/
The bar also serves good food.
All meetups cost £2 (or donation if times are tight) to cover my web costs, which will be payable on the night. Please let me know first names of anyone you may be bringing with you in advance. Please also adjust your attendance if you decide not to come at any time; it may make a difference to the booking size.
I'll look forward to chatting with you (if I get the chance) very soon!
