They sell it here in the US but it's $50 a bowl. Do they have this in VN?
I think there is. I did a search and found a place called Tom Hum Pho on 220 Lê Thánh Tôn, Phường Bến Thành, Quận 1, Hồ Chí Minh, Vietnam but no reviews yet :/
Tom Hum = lobster
There is also Banh Canh Tom Hum I want to try so badly (many places in Vietnam)
There's also that $100 pho at Landmark 81
Pho is a traditional dish of Vietnam that has been mentioned in many world-famous culinary sites, and is also a familiar dish in the daily life of Vietnamese people. If you have the opportunity, choose Pho to experience, it is also very interesting.
This is a basic bowl of Pho
