Public platform ratings, shown as of when we last checked, kept separate from our own Taster score.
Why it matters
A substantive tendon option, not just a tempura roll. Count this combined venue once; retain the historical Don Don Tei identity and avoid claiming a verified corporate merger.
Dishes highlighted in the coverage we read, not a promise of today’s menu, and not our own picks.
Listed on sources checked today; live operation was not phone-verified.
In the press
What critics and reporters have written, attributed summaries, not our own review.
A 2011 Monster Munching report preferred Don Don Tei’s tendon to its cutlet bowl, describing the sauce-soaked batter and rice as the appeal. The report is useful context for the tendon format, not proof of today’s kitchen or operator.
One old account; current merchant is listed as Mugimaru / DonDonTei. Retain that naming-era caveat.

How ratings work
Diner ratings. We show each platform's public rating as of the date we recorded it, on a 5-point scale, with a link to the current rating. Our tempura rating is our own firsthand tempura score, always kept separate and never blended in.
Diner consensus. We combine independent platforms into one score, weighting each by how many ratings back it. Platforms that share the same reviews are counted once, and the consensus only appears with two or more independent sources.
Independence. How we rate and recommend is never affected by any advertising, partnership or sponsorship. Ratings and reviews remain the property of the platforms they come from.
