Last time we went (a couple of nights ago) we both had soft shell crab to start, with their standardly delicious bread and butter alongside. If you don't know Thai food, this might freak you out a bit, as the whole thing is deep fried in tasty spices and you crunch your way through the whole creature, shell and all. It was perfectly cooked and the dressing was deliciously sweet and citrusy, with a crisp salad (no hint of a wizened tomato). Be brave! It's worth it.
For mains we had 1) the pork and 2) the ricotta, tomato and herb pancakes (which you can have at starter or main course size - a handy feature of several dishes on the menu), both of which were excellent. Too full for dessert, one of their Union Coffee espressos went down well.
