Kien Giang is really good. I must say, they're legit. My girlfriends bun rieu was pretty intense and honestly a little too crabby for me but they're not holding anything back.
My pork porridge was awesome, it was a special though, so there's a chance it might not be there when you go. I haven't been back because I've been trying to try everything but it's been hard not to go back since it's on my way home.
