Tsukemen Gonokami Seisakusho
Time Out says
Located behind Shinjuku's Takashimaya department store, this hugely popular tsukemen (dipping ramen) restaurant has hungry customers lining up an hour before the opening time, especially on weekends.
Starting at ¥880, the ebi (shrimp) tsukemen is the hero here – unlike regular ramen, this is eaten by dipping thick, chewy noodles into a hot, dense soup made with a heavy helping of shrimp. There are a few variations on the theme, including ebi miso tsukemen and the more daring ebi tomato tsukemen (both ¥950).
Toppings range from the conventional, like ajitsuke tamago (ramen egg) and chashu pork, through to more surprising options such as basil sauce and mozzarella cheese. Keep in mind that the standard serving is a generous 270g of noodles, so if you’re not feeling famished, consider getting the smaller size.
