The one that comes to mind was at the late, great Dodin-Bouffant
in Boston, a second-story walkup on Boylston St. My father and I
were having a nice tranquil meal when there was a bit of a commotion
at a table across the room - a waiter had gotten a bit overenthusiastic
about a flamed dish, gotten a bit flustered, and it appears knocked
the chafing dish onto the carpet, which alit and also set the tablecloth
on fire. Within a few seconds, though, people were by stomping on flames,
squirting extinguishers, and so on, so I just kept savoring my sweetbreads
en croute and watching the goings-on. At some point Pritzker, the chef,
came over, apologized for the fuss, and chatted a bit about the food. I
don't think we asked for or got any sort of compensation.

There have been a couple other alarms in my past dining life, but
I don't think any had any actual fire attached to them.
