Tbh, the post house was only good in it's first incarnation really.
The fosters?, did a good job with the place, but it was crippled by low footfall and high rent, also, I think they put too much emphasis on the food side.
At best, they should have just did average pub grub, and a more superior banquet on a need to basis, like for weddings events and such.
Also the interior space is a little awkward, there's numerous rooms and passage ways, so it's difficult to make it a club really.
Going forward, I'm not sure what you can do with the place, the last 3 failed for various reasons.
Fosters spent way too much on the place.
The casa team did the math, n realised the rent would pull both it and casa down if they continued the venture, so pulled out.
N the last lot, we're hit by falling numbers of people out, n I don't think they did enough to differentiate between that and the post house, so again, a failed idea.
