Shokkan is located In the basement floor of a random building in Shibuya but let me tell you this place was awesome. We went during lunch time and we knew it would be good as soon as we noticed the wait outside the door before it even opened and how it was completely packed within a few minutes after opening. This Japanese restaurant serves three options during lunch: Tsukemen, Today’s Fish Set, or Today’s Meat Set (each for 1000yen).
I highly recommend their Tsukemen. The quality is quite high considering that it’s not officially a tsukemen or ramen house. The tsukemen comes in 3 different flavors: Soy, Sesame Miso, or Curry. We ordered the soy and I really loved it. It’s nice that it comes with all sorts of toppings and also includes a choice of rice or rice crackers so you can eat it as a porridge at the end. Their other dish is a Fish of the day plate and it was Shrimp and Eggplant on the day I visited. It was good as well but the tsukemen was the highlight. Looks like they have this restaurant at Soramachi too with a different menu. Check it out!
