Long Bar is probably the only place in Singapore where you can litter without getting fined. The "carpet" of peanut shells lining the floor is no accident - patrons are given complimentary sacks of nuts as snacks, and are even encouraged to throw the empty shells on the ground as an ode to the surrounding nut plantations of the past.
This is also where the iconic gin-based Singapore Sling cocktail was born way back in 1915, thanks to Raffles bartender Ngiam Tong Boon.
