Customer Review Summary

Reviewers consistently point to the ramen as the draw, with the Tan Tan Tonkotsu Ramen praised for its rich broth and bouncy, chewy noodles, and the Black Garlic Oil Ramen singled out as fragrant without feeling heavy. Close behind, the classic Tonkotsu Ramen gets called out for its rich soup, and diners also mention dumplings with generous filling, a katsu curry, shrimp croquettes served fresh and crunchy, takoyaki, sesame spinach, and chicken yakiudon. Vegetarian and vegan options also earn praise for quality. Several reviewers highlight the staff's care, including one account of a server bringing tissues and candies to comfort a crying child, and multiple diners describe quick food and friendly service. One reviewer's second visit reinforced the return, and portions are repeatedly described as generous.

  • chan carol
    The Tan Tan Tonkotsu Ramen has a rich broth and very bouncy, chewy noodles. I also loved the Black Garlic Oil Ramen—it’s super fragrant but doesn't feel heavy or oily at all. Very generous portions of meat and noodles too! Don't miss the Shrimp Croquettes; they are served fresh and crunchy. Definitely coming back.

How this listing is sourced

Where the data comes from
Name, address, hours, contact details, amenities, ratings and review counts come from the business's publicly available profile data — not from the owner and not from paid submissions.
How it stays current
Listings are re-checked in batches against their public profile, and anything reported as wrong is corrected at the source rather than patched on the page.
How it is ranked
Placement is never sold. Every business on the page is ordered and compared using the same public signals, so an owner cannot pay to move up.
