You could see if the
"Mapping LTH" trick I posted about helps you narrow things down: here's
a link to a Google Map of posts from LTH in the Lakeview area. It's not perfect, as you'll see the first hit is for a thread mostly about Kizoku, which is in River North, but Matsuya does appear later in the thread.
In any case, it may help both stimulate memory about what's around there and lead you directly to places where LTHers have had opinions about those places.
This trick really only works for posts when people adhere to the board convention of including the full address of a restaurant. It would be cool if we could put in more hints, but check it out...
