Is this your business? Ask for removal or report a problem

Its details here come from its Google listing, so the place to change them is the listing itself.

What would you like?

A removal is checked with the business first, and a confirmed one takes the listing off every page of the directory at the next update.

Ratings and review counts are Google's, as listed in October 2026. Phone numbers, websites and opening hours are the ones each business lists. Nothing here is paid for or verified by Calso. How the ranking works.
