Buying whisky samples at stores in Japan
sorry if this a silly question… but what’s the process for buying samples at liquor stores in Japan? I saw the open bottles when I was there a few years ago, but didn't realize you could purchase samples to take away. Do you just go to register and say you’d like to buy some samples, or do you bring the open bottle to the register?
also, any stores you’d recommend in Tokyo or Yokohama, specifically for buying samples?
thanks!
