pho kim long is probably the most well known pho place of las vegas. it is located in the heart of chinatown and the parking lot is quite small but i've never had a issue finding parking.
i usually always order bun bo hue and occasionally pho with meat balls, they're both alright and i've had better elsewhere. i'm sure other foods are good but i never cared to try.
this place is always packed and keep in mind it is open 24/7. you'll mostly see traffic at late night when people come here for drunk munchies and early morning for hangover food. it is basically rachet central up in here with girls coming in in their club attire limping all over the place, lol.
the service is kind of shitty, you often have to flag down a server to refill water but most of the time you're drunk so you don't really care.
i recently had a seizure attack here and they had to call the paramedics for me so i probably will not be returning for a very, very long time. (SO EMBARRASSED)
but i do recommend giving this place a try and you can be the judge yourself.
