I've been in Ninja City twice for drinks and not-so-delicious snacks. In fact, Dylan and Bac were both there to greet me, since Bac and I are Case alum (and Dylan briefly attended).
My first visit was during a Cleveland trip in August. I had the ramen soup, which I found to be sub-par (borderline mediocre). The ramen elsewhere in the country puts this to shame, but you might not know that if you've been in Cleveland all your life. Broth was pretty weak and noodles were meh.
Second visit was for drinks. I brought a wedding party in for a round of shots on the way to photos. Bartender definitely watered down the drinks.
