... because it's been sitting next door to the Roppongi Hard Rock Cafe since 1987.

Quoting from Wikivoyage:

Tony Roma's, 5-4-20 Roppongi (next to Hard Rock Cafe), ☏ +81 3 3408-2748. Step out of Japan and into the United States; the bilingual staff and English-only menu might make you forget you are in Tokyo. The restaurant features their trademark ribs, worth the price which starts at ¥1880. The Texas Mud Pie is the cure for tiny Japanese desserts.

Apparently, this Miami-based baby-back-ribs chain has seven locations in Japan. (And two in LA, but none near Bob or me.)
