Mm, now I'd buy that for a Dollar!
On the theme of Rant -vs- Review, there are few reviews worth reading, yet most Rants are entertaining. Any restaurant review should be 98% Attack, and 2% Thank You to the marvellous valet / cloakroom girl / interior designer. Anything else is just too bland
Anyone who's worked professionally in service knows when things are not right and unfortunately - in Zürich in particular - things are rarely very good. It's a miserable rule of service that the customer will ignore the good and highlight the bad, but that's what makes the job such good sport - and rewarding when done right.
I vote for more educated rubbishing of poor service and lousy meals. Not: 'Do you know who I am?', more: 'Who are they taking us for?'
The culture here is - perversely - not one of criticism when it comes to restaurants. "Alles gute xsi?"* is rarely replied with "Ja-in, leider nicht perfect..."** rather "Superxsi..."
He who pays the bill decides if it was nice or not, for reasons of decorum
My in-the-field tip is to complain in situ
to anyone who'll listen, but NEVER at the table. Take the complaint to their territory, where they'll be offguard to patrons confronting them. It's also polite to raise stink away from the table
Invariably you'll get a better and more prompt result by having a quiet word with whoever on their turf.
Name and Shame!
*'Was everything alright?'
**'Yes and No, unfortunately not perfect..."
