What goes swish, swish sizzle?

Last weekend (April 20) Shizuka and I went to Tokyo, just for a visit and to do a bit of shopping. Because I am of greater proportions than your average Japanese gentleman I have found it difficult to buy shirts in Niigata. Most shops stock only S M and L, I'm a 3L depending on the cut (see arm in picture). Toyko is not your cheapest place - the Schinkansen (bullet train) tickets alone are £50 each way. Hence the title:
Qu: what goes swish, swish sizzle?

We stayed in this 3 star hotel for one night around £70 - £80. Nice room, well located and looked after the shopping when we sent sightseeing
