SIN stands for Service Industry Night but everyone's welcome as far as I know. On Wednesday November 26th From 10 pm-close (2am) its 1/2 off draft beers and Victoria has a decent selection of them. Worth a try if you've got the hours.
Things can be a little crowded just an FYI, as they scuttle the dining area and shift all traffic to the sizable bar area. Its festive and lively and loud but the prices are much improved from the usual rate.
