Another place that gained fame thanks to the 11/26 attacks, this bar/cafe features a nice mix of locals, expats, and foreigners all coming together for mediocre food and cold beer. You can even order "beer by the metre" -- though hopefully you are sharing it, not keeping it all to yourself! To see photos:
