Go to that place at the usual hours and you can often verify it ;-)

Although it's a good idea to have verifiable tags (for various reasons), 
it's not necessary to take the wiki page you've mentioned as a 
"verifiability law", which can never be excepted.

Would be nice if someone comes up with a way to make this tag more 
verifiable, but if there's no better way to get this information into 
the database, than "unverifiable" info is still better than no info at all.
