Just to be clear, we visited Penylan's subsidiary location which is under the 'Cheese Pantry' banner located in the Cardiff Indoor Market.
Exploring central Cardiff we luckily stumbled upon the indoor market and the Cheese Pantry. They stock a good range of cheeses across many categories and we left with a few different varieties. I shouldn't admit we ate the whole wedge of a sheep milks cheddar in the hotel room that afternoon!
We were served by a friendly and knowledgeable bloke called Owen, who was more than happy to oblige with providing tastes of quite a few of the different cheeses before we settled on the three that we eventually bought. He was helpful in guiding us towards certain suggestions based on our tastes, he certainly knows the range.
If you like cheese, do yourself a favour and pop in for a wedge or two of some fine artisan cheeses.
