Here are a few photos of the area around Avenida de America. The
area southwest of A.d.A. is one of the most exclusive ones in
all of Madrid. (i.e. incredibly expensive for everything, even
for a cup of coffee or a piece of chocolate.)

I've eaten at the Wok above, and it's pretty good though the
service was a bit slow. I've eaten at a Frescco's and was happy
with it, but I haven't eaten at this particular one.
