Dr. Fern is a speakeasy in Hong Kong hidden inside a passageway directly outside a train station. It sort of looks like a doctor’s office out front, hence the name. For the most part, it’s a gin and tonic bar, although you can find other cocktails like a Negroni. Once you’ve gone inside, however, it’s clear you’re expected to order a gin and tonic. They have an entire menu (called the Doctor’s Order) dedicated to hundreds of gins that you can pair with quite a number of tonics. The combinations are almost endless, which means its a nice place to frequent if you’re a fan of GNTs. It’s a simple premise but because gin can have so many different notes, your experience will always change.
