The shop is in Ningyocho about 3 or 4 blocks from Exit A3.  Go out the exit and turn right.  Go about 2 blocks to the light (there is an Indian restaurant on the right side) and turn right.  Go a block or 2 down and Brozers is in front of you on the right.

The shop was so busy that people were waiting outside for a table.  I hear it is like that every day for lunch, even the weekends.

If you go there, ask the for the manager Yuuta and tell him you want "Nathan's Burger."  Of course, then you will get a plain cheeseburger (meat, cheese and bread only) that is extra extra extra well done, so maybe you don't want to do that!
