The Thai Orchid is a good restaurant but it is a bit pricey. The portions are not large, except the desserts which are massive and really good value. The wine is quite expensive (the same house wine is £4 cheaper in La Casa Loco 5 minutes walk away).
What I really like however is the flavours of the food, spicy but not overwhelmed by heat, with the subtle flavours also showing through. I would recommend this restaurant but be prepared to pay for what you get. The service is vey quick though, esopecially considering there are only 2 front of house staff. I would recommend booking if you are arriving after 20:00 to 20:30 time as it gets very busy from then on in.
