Alternatively...

You could shell out 17,000yen and get this: http://blog.livedoor.jp/osakanohonnm.../51521712.html
you even get fugu in the deal

I'd probably stretch my lunch budget here: http://blog.livedoor.jp/osakanohonnm.../51519249.html (3,675yen for this menu)

And don't forget that ordering beer, wine, sake or soft drinks can double the price of a lunch menu. Remember that some sort of drink (tea or water) will always be included.
