Just a huge online store!
It's easy to get confused in the halls. But the staff is always as polite and helpful as possible - they will help you navigate (they will even take you away and show you the shelf - how many times has it been... although I only ask you to "show me where").
A huge selection of goods. And recently I found out that you can also buy something edible there! Alcohol is not mine. But rare species can also be found...
