There is one place in Berlin which's Tonkotsu Ramen stands above all other Ramen dishes in Berlin, the hyped Cocolo Ramen. I was there yesterday and althought I had to stand in line for 20 minutes, the food was completely worth it. If you like Ramen, this is your place in Berlin.
What I love the most about Cocolo's Ramen is its broth, super deep and rich!
