Two of us stopped here on the way back from climbing Snowdon. We'd noticed the place on the way up, particularly because of its signage saying that dogs and muddy boots were welcome, and that people were welcome to go in and eat their own food in front of the fire (the tea shop doesn't serve full meals, but does serve snacks). It seemed very friendly and welcoming.
Steffan - the owner - was very warm and friendly. In fact, many similar places could do with lessons from him in how to treat customers. He was very attentive and friendly towards everybody, and it was a delight to watch. We ordered a glass of beer, and a drinking chocolate. The drinking chocolate was absolutely delicious, and the (locally brewed) beer was welcome too. We initially sat outside enjoying superb views, but finished inside by the fire, where we had an enjoyable chat with Steffan.
The drinks were a little expensive (£6 for a drinking chocolate and a 500ml beer), but the whole experience was rather a treat.
