i've eaten at the original thairestauranta few times now, and have always enjoyed the food.
the last two times i ordered the gai fai - a very hot meal, and loved it. we had the fishcakes to start which was also very nice.
two people at our table got given the wrong meals, that were meant for a different table, but this was corrected quickly.
the whole chicken is a very popular choice here too - someone at our table always orders it, and it's too big for one person to eat by themselves.
