Handy hint for anyone going to SECC. Park outside Stereo in Kelvinhaugh Street (Although I don't THINK it's called Strereo now think it's The 78). Anyway park there, it's well lit and very safe. Walk down Kelvinhaugh Street towards Clyde. There is a footbridge over Main road which takes you in to SECC car park. Literally a 5 minute walk from the pub.
It is only 2 minutes off M8 and saves £4.50 plus no hassle of queing to get out car park. It's near Charing X.
