For mains, you can choose from many different soups, including pho (a combination beef noodle soup), rice or noodle dishes with your choice of meat, and a whole lot more. There is simply too much to list.
Even if you are not a big fan of Vietnamese food, I am pretty certain there will be something there that you would find delectable.
I went there with a couple of friends for lunch, and even though the cafe isn't huge, the majority of tables were filled. I am not sure if they are so busy that you need to book, but in the event that they are filled, you can simply get a quick Vietnamese bread roll or main dishes as take away.
