4 star because I would go back to give their food another try.
But just for the one time experience, I'd give it only a 3.5 star.
We went there for dinner, and got a summer roll for appetizer. The roll was served at room temperature, which wasn't all that good. They should really chill the ingredients before serving it.
For entree, we got a lemongrass chicken rice dish and a spicy beef noodle soup. The chicken was actually unbelievably tender! And the noodle soup came out with a lot of raw veggies, just like pho. Soup was tasty, but the noodle was so so.
Got a vietnamense coffee...it came in the SMALLEST cup you can imagine with the MOST amount of ice possible. That's definitely a sign to never order their drinks again.
But we'd go back for the food, just to try a different dish next time.
