MerchantCircle is having a party at Nola. I think this used to be called Pearl's -- the source of this famous Internet story. I've never met Brian -- but I have immense respect for him. I did work one summer with Lucille, his sister...

I work in the very center of the city of Palo Alto, in a nice office
building. We are surrounded on every side by restaurants, hotels, and so
forth. But we are a computer company, and so our building ends up needing
a lot of electricity. We use about a megawatt (1 million watts).
In order to deliver a million watts of electricity to an office building,
you need a very large transformer. These transformers are too big to put
on poles, and besides in quaint downtown areas nobody likes those poles
any more. So the transformers are put underground. The million-watt
transformer that powers our office building is located in an underground
vault in the middle of a walkway that leads to City Hall. The transformer
is about the size of a small car, and the transformer vault is about the
size of a one-car garage, except that the way you get in is to climb down
a ladder from the street level. The top of the transformer vault is well
ventilated, because a million-watt transformer generates a lot of heat.
Several fine restaurants are near this walkway, along with a bank, an art
supply store, and so forth. There's a lot of foot traffic. This being
California, where it never rains, and this being Palo Alto, where it is
always springtime, the restaurants have outdoor seating areas that are
Recently the patrons of one restaurant started to complain that there was
an unpleasant odor in their otherwise idyllic outdoor seating area. Soon
the Health Department was called, and they quickly determined that the
odor was caused by rancid oil that had seeped into the sidewalk. Further
investigation showed that the source of the rancid oil was overflow from
a nearby grating. The grating was marked "City of Palo Alto Utilities",
so the utility department was called.
The utility crew quickly discovered the problem. The oil wasn't really
oil, it was molten deep-frying grease, which was molten because it was
being kept warm by a million-watt transformer. The entire vault was
completely full of used frying grease, about 2000 gallons of it, which
was enough to completely cover the transformer. The heat of the
transformer kept the grease from solidifying.
Police quickly figured out what had happened. Every night for quite a
number of years, one of the nearby restaurants had, at closing time,
emptied its fryer into the transformer vault, thinking that they were
dumping it into the storm sewer. It's quite illegal to dump grease into
a storm sewer, of course, but they probably figured they would never get
Transformers do occasionally overheat; this is why they are kept in
concrete vaults. If this one had overheated, we would have had the mother
of all grease fires.
Last night they shut off all of the electrical power, pumped out the hot
grease, washed out the vault, and replaced the transformer. It's very
fortunate that nobody was killed.
Today's "daily special" menu did not include the usual fried fish.
