I visited Tiien Thai on Thursday 5 March 2020 in the evening, a weekday during term time. I was with five other people. This was my first visit. I used Google Maps to find the restaurant, which was easy and led me straight to the right place. I parked in the street nearby the restaurant - parking was easy. The restaurant comprises of one reasonably sized main dining area with plenty of tables with full table service. The team were very friendly and welcoming - we got everything we ordered in good time and enjoyed the experience. I enjoyed a selection of shared starters including chicken satay, sweetcorn cakes, spring rolls and prawn crackers, a chicken and cashew nut stir fry with coconut rice for my main course and banana fritters for dessert. The food arrived hot, was well presented and tasted good. There was a good selection of food and I found something that appealed to me easily. The food was reasonable value for money, I paid around £30 for three courses and drinks. We had a bit of a discussion around use of a discount offer - as this had not been mentioned at the time of booking it was not allowed but we were offered some discount instead - kind of spoilt the evening a little if I'm honest - either offer discounts or don't, why add T&C's like mention when booking, is it so they can reduce the portion sizes for you or something, just makes things look a little sinister but the environment was nice, food was good and the service otherwise was perfect so all in all a good night! Overall I really enjoyed my visit and would come and visit again.
