This place is very busy every Sunday during lunch time! I come here on occasion when i'm in the area. There's a Pho mi 99 near my house as well and tbh they are all the same. Service is fast, there's a line up (short one) but it gets cleared quickly.
A must order are their spring rolls! it good to share and it's super tasty with the dipping sauce. If i'm not ordering a Pho bowl, i usually get the 501... all the time! chicken, pork chop and egg with steamed rice! mmmmmm! for only 8.50! the portion is huge btw.
This is a family place so expect it to be really loud during lunch time on weekends, not a great place to catch up that for sure.
