When your looking for a good place to go out to later in the evening, Slippery Senoritas definitely fits the bill for a good time bar/club. Featuring a live Filipino house band that is usually pretty good and gets the crowd up and dancing, and bartenders that repeat some of the tricks from the movie Cocktails - SS is one of the best places to be on Penang. They do a good job on the mixing of some strong drinks and have Tiger beer on tap.
SS is one of several Garage complex clubs and has a good draw of different people that start coming in later in the evening. The music is even better when the house DJs start in playing Latin to music fusion of R&B and house and current hits. The best time to get there is after 10pm, and watch the place start moving on Wednesday to Saturday nights. The SS also has a pretty good and varied menu as well.
SS is a fun enough time that even I found myself closing it out 2 nights in a row. Getting a cab back to a hotel from the Garage complex is not a problem, being Penang Road is right out front.
