Overlooking the intriguing ruins of an old monastery, The Castell Mynach near Cardiff delivers traditional British pub cuisine in a beautiful country atmosphere, but remains comfortably close to the city. The seasonally prepared food can be enjoyed in front of the cosy log fire, or al fresco from the beer garden with views of the monastery.

Hearty Sunday roasts and trusty British dishes head The Castell Mynach menu, and a range just for kids offers mini versions of pub favourites. Signature Vintage pies offer fillings like beef & merlot with buttered peas, while The Castell Mynach ‘Vintage classics’ menu includes lemon & garlic-roasted chicken with seasoned chips.

Paying homage to the Great British pub, the Vintage Inn bar stock includes cask-conditioned beers, real ales and a meticulously compiled wine list. Thirst-quenching offerings include seasonal non-alcoholic cocktails and freshly-pressed juices, and rich coffee is brewed freshly throughout the day.

The Castell Mynach is a mere 7-minute drive from Pontyclun and is in .

    This is one of the best venues for a Sunday roast. We have tried a few different places locally but this is by far the best.

    Great food, friendly service, lovely atmosphere.

    Good service.
    Lots of food on the menu not available on the evening we went.
    Steak was not good - very chewy and no flavour.
    Trifle was probably the worst I've ever had.

    Restaurant was very care worn and uncomfortably hot. Food was poor and not a place I would visit again any time soon.

    Really y lovely meal.. A little disappointed that there is no longer a dedicated Gluten Free menu although the staff did their best to help this meant that my choice was very restricted.

    Very friendly waitress, very cheerful and efficient. Average pub grub, nothing brilliant but OK for an evening with friends. The starter of scallops and king prawns I garlic butter with rustic bread was delicious, the garlic butter was best I have ever tasted. Haloumi in a batter and deep fried was unusual and different, it came with a tiny pot of gherkin relish but could have done with a bigger zingy and tasty relish. The Eton tidy cheesecake was tasty but could have been presented a bit better instead of just having the Eton splodged on the cheesecake.
