Vietnamese Food Recommendation

Hi, I'm a Vietnamese and have been living in NYC for 14 years.

I have done an extensive list and discussion of Vietnamese food on r/FoodNYC, you can find my extensive post here.

I plan to spend 10 days in London, as this is my second time visiting. After browsing a few restaurants' menus, I find the Vietnamese food scene in London to be very promising. But, having spent 3 days in London on my first visit and planning to relocate to London at one point in the future, I am geared up to give Vietnamese food in London a proper run for its money (or my money).

Given my familiarity with the cuisine but lack of familiarity with the city, could you recommend some of your favorite Viet spots in the city?

If my opinion weighs any ounces, I will promise to make a proper follow-up on this post, as a thank you.
