My experience was staying at the Antrobus hotel after visiting Stonehenge, and being delighted by the Siam Smile Thai Kitchen, that is situated within the hotel itself. There is a menu in the room and small details help to distinguish the arrangement that is clearly symbiotic; like the modern desk, mirror and potted plants that surround the menu in the room.
The menu is well constructed and explained, the dishes are interesting and the owner Joy has a lot to be proud of here. I chose a vegetarian meal, Vegetable Tempura, Tofu Panang and Steamed Jasmine Rice - the flavours and cuisine were well balanced and presented. I had two large Thai beers and sticky toffee pudding afterwards. The menu says nothing about vegan and gluten-free options, but Joy listens to her customers!
Cold Thai beer is stocked by the restaurant, but the hotel bar can send other options to your table in the attractively decorated wing. The key points are the food and the service, worth going back and maybe visiting their sister shop - Miss Bubble (street food).
