Most people won't go & those that already do probably don't read the Guardian!
Can only really go on whether you enjoyed it or not.
On a similar note read a review of a restraunt near me & it likened the customer service to something out of Fawlty Towers with the waiter being somewhat of a curmudgeon. That was it - just needed to go and see it for myself - was nowhere near as described the review & food was great.
Still an enjoyable read
Cheers
