Re: what makes nakhla so hot?
Nakhla is great and there are a lot of fans here. It is definitely old school, so if you are used to very drippy candyish shisha (read: starbuzz, fantasia, etc) it will be a change for you. It is drier, unwashed, and don't rely on gimmicks (e.g., no sloe gin peach fuzzy navel, chocolate cherry martini, or sex on the beach). I'd suggest that you pick a fruit flavor or two that you think you'll like and read a few reviews.
Nakhla is usually available in local smoke shops. Of course it depends on the shop, but where I am the dudes are shady and will keep that stuff on the shelf forever (I actually found a box the other day dated 2002). I am trying to find a good online source for Nakhla where I can be assured of the freshest product, and also a wide variety of choice.
