I visited Haru Ichiban this past weekend. Just about every customer and employee there was Japanese, so it made me feel right at home (as did the close seating quarters). They had quite a selection of different types of ramen: tan tan men (what I ordered), seafood ramen, chashumen, etc. All of them were available with different broths including miso, shoyu, tonkotsu and possibly one other but I don’t remember.
The tan tan men was delicious - I can’t complain, having not had real ramen for quite some time. It wasn’t very pricey either - the cheapest bowl of ramen was only $6, while my tan tan men was $7-8. Good creamy tonkotsu broth. The noodles were good too. I’ll definitely be visiting again…
Let me know if you visit any of the other places in Atlanta.
