Container Park is one of my regular spots, so I've been to JinJu a handful of times now.
The shop itself is small, which is my only complaint. If more than 5 people are inside at one time, it gets cramped.
However, everything else about JinJu is top notch. The customer service we receive there is always above par. It's always the same woman working there every time I go and she is very knowledgeable about the products and even the history of it all.
One of the things that I love most about JinJu are the promotions. Some of their chocolates are pricey, but they have a Yelp check in deal going on right now and last time I went, they had a promotion for Pokemon Go players. I got a free full sized chocolate bar out of the deal that I probably would have never tried, but am dying to go back and get.
Some of my favorites that I've had are the pecan clusters, pretzel sticks, and the Elviiiis chocolate bar. If you are a lover of desserts like me, this place should be on your list.
