Yep, went in and I can see exactly what the concept is.
Basically, its a small cash & carry - small version of musgraves. Probably originally planned to service small stores / food outets in the area and then they cam up with the idea of allowing the public in.
If you want large bags of dried fruit, sugar sachets, sauces etc, then its reasonably good, as for the standard items, they are similar prices to tesco etc but with quite a small selection.
A sort of branded Lidl could be another way of putting it! - They even have the Lidl style special offer items such as garden forks & vacumn cleaners.
I'd award it 7/10
