Hi,
Well, there are several ways.
First, you have the HikaShop wishlist module that you can configure via the Joomla modules manager to display the content of the wishlist in a module, like you can have for the cart.
Then, you can also create via the Joomla menu manager a menu item of the type HikaShop cart display or cart listing and select the type "wishlist" instead of "cart" in the settings of the menu item.
Similarily, via a menu item of the type HikaShop user control panel, you'll get a link to access your wishlist(s).
