How do you make a "silk dragon" martini?!
EDIT: Red, pink and green, sweet... well, certainly not a traditional Martini by any means. I'm going to guess Midori was the green layer, since that's a pretty common base for fruity drinks in sushi bars. It might be another name for a Field of Hearts, which is made by layering Midori and strawberry liqueur around a mixture of Frangelico that's been tinted.
Answers: Do you know anything else about the drink? Was it sweet, was it like a regular martini? It could be a custom drink served only by that restaurant, or else a variant on a martini or another kind of drink. Knowing a bit about the taste would help.
