For casual lunch/dinner of Vietnamese cuisine, a chain restaurant named "Nha Viet Nam (ニャーベトナム)" is convenient. Their branches are in and around Tokyo. Interestingly, whenever I go, most customers are women. Here, women tend to prefer South-Eastern Asian cuisine rather than men (I don't know why). I also visited with a friend.

This chain is run by a Japanese company, but staff was Vietnamese people which makes the atmosphere authentic. But the tasting might be adjusted to some extent for Japanese preference. As they provide variety of choice, it was difficult to choose from menu book! Lunch is available from JPY850 and the one I selected was JPY1,300 with pho, Vietnamese curry, salad and fresh raw spring roll. Pho, Vietnamese rice noodle was a bit salty but delicious. Chicken stock made the taste rich. On the other hand, curry was so-so. But if you want to taste Vietnamese cuisine casually, this chain is recommendable. My rating is 2.8 out of 5.
