Hi, It is easy to find out. You just find the outet of Shwapno Near bijoy nagar you will find out. You can tell your care taker of your house. They will find out for you. I hope you will find out soon. Have a good day.
Usually, drinking is not common in Bangladesh, so I doubt you are going to find any good drinking place. You won't find anything good as soju either! >.< So good luck.
