Well, it's open late... that's why everyone comes here. If Kinh Do (a block away) didn't close at 10 p.m., I would've been there. On a Saturday night at 11 p.m. we were quoted a 30 minute wait time but ended up only waiting 10 minutes for a table of four.
I live by Little Saigon in Southern California so if comparing to the pho there, Pho Kim Long's pho and bun dishes are normal/about average. There wasn't anything that stood out good or bad about them. I had the vermicelli with grilled pork and egg rolls. My friends had the pho.
Drinks here are a tad expensive. I think it was $3.50-$3.75 for Iced Coffee, Fresh Lemonade with Soda, and Preserved Lemon with Soda.
The service here is good. Numerous servers came to check on/take our order. If I was craving some late night pho after a night out on the town, I'd come here again.
