If you're a lover of Thai food then Thaikhun in Bath could be exactly what you're looking for. As someone who used to live in Phuket, I can assure you that the decor was clearly well thought out and created an authentic atmosphere. They had signs in Thai and signs for popular Thai shops and the drinks menu included many drinks that are found in Thailand.
The food was delicious. We ordered a mixture of food to share and the Thai Red Curry and Chicken Pad Thai was my personal favourite. Unfortunately, I was too excited to eat and forgot to take photos of the food but I can assure you it looked as delicious as it tasted!
The price was super reasonable we ended up paying £7 per person, although we were all drinking tap water as it was a super hot day. The location is also perfect as it is in the newly refurbished Southgate centre.
