we regularly come for the tom yum noodles here, which are amazing, possibly the best we've had in sydney. the pork-based broth is incredibly flavoursome, very tangy and hearty. the fried wonton sheets add an interesting texture to the dish. the tom yum noodles are very reasonably priced, too, at $6.9 for a small bowl. if you're not accustomed to spice, it's best to start at level one and add your own.
service is always very fast, and do dee is usually open until midnight too - making it great for a late snack. the rest of the menu is possibly a little wanting. for something sweet go for the thai iced tea. some of the other drinks and desserts we've had - the pandan juice, a shaved ice dessert - we found a little sickly sweet.
overall would definitely recommend do dee for its tom yum noodles.
