Although it is better to experience real Thai food in the evening at the old bakehouse, the daytime food is of the equally outstanding quality. By day it is a busy, very atmospheric coffee shop/ restaurant, with very friendly and excellent service and it also has the food to go with it. You cant really express the word for it other than try it for yourself. I must inform you though, that it is advisable that you book a table, as it is very popular and quite usually fully booked.
