For the :beer: , it's below Madhan Pub. Okay, take the Road opposite to Forum and you will a Bharat Petroleum Gas Station on your left and just after that you will see a road going to the left. Take the left and probably the second or third shop is that LEWIS. It's their branch and there's hardly anything there. Even the main Lewis doesn't have anything worthy.
He does have the standard stuff..Dunlop picks and slides..Givson guitars..GB&A guitars..Stranger and marshall amps etc ..so if you live near/in Koramangla and dont wanna travel far for some guitar stuff, u can always go there..
