Nestled on Kenmare St.- that ugly strip where Little Italy melds into Nolita/SoHo- Cocoron Soba isn't a spot you'd pass by and notice right away (they also have another shop on the LES, on Delancey St.). But enter inside, and you'll find a bustling, authentic noodle shop, complete with chefs seriously cooking behind the wood counter.
You can grab your noodles hot or cold, although if you grab hot make sure to eat your noodles as fast as humanly possible so as to not let them over cook. Don't worry, it's never rude to slurp. The cold come on a beautifully presented platter complete with a dipping sauce that takes some chopsticks skill to dip the noodles without making a complete mess.
Cocoron means "heartwarming" which is exactly what you'll find here, filling, Japanese comfort food.
