The pho is alright but definitely not the most tasty pho restaurants in the area. The pho broth tasted less beefy and I don't understand why there is only one size, have a L or XL i'll gladly pay the difference for a bigger bowl just to be full and not hungry 1 hour later.
Service is not that attentive, water refills are hard to come by unless you get their attention.
Overall, I would choose another pho restaurant to go to, like Pho house, Pho XE Lua or Com Tam Dao Vien, which all three have different bowl sizes including XL.
