LP too bloodly crowded on Sun. Personally for me on Sunday the best is still Ipanema. Cost about $30 for a jug of beer and just go in and fish. Look for tables with single ladies and just ask permission to put your jug down. After awhile share your beer around. Normally cost about 2 jugs to get at least a contact.
Even if get nothing also fun bcos alot of different scenes inside. Stick to the side from toilet and pool table upwards. Less noisy and more newbies. Just be friendly, smile more and just open your mouth to talk.
For non drinkers, can hang around outside and just chit chat with anyone that catches your eye. However take note they likely want to go in so be prepared to pay for beer. Nothing is free so if not prepared to pay then just use your left or right hand...
P.S...never look for tables with bangala boyfriends. Waste of beer and time.
