My partner and I have been to Phi Yen several times over the last few years, but mainly with another couple, This time we went solo and the experience was a little different.
Firstly the Negatives for me with Phi Yen is firstly - Parking, it is mainly in a residential area with street parking, plus there is a Hotel across the road which makes the Parking even more challenging, the only other Negative is the NOISE inside, very tinny and echos quite a bit, extremely hard to have a conversation with friends (it's annoying to have to yell when your at dinner)
The reason we keep going back to Phi Yen is due to the Delicious food, (maybe a little too much onion in some dishes).
We started with Spring Rolls, which to us were outstanding, Then I ordered the Lemongrass Chicken and a Bamboo Chicken curry, both were extremely tasty, we also had steamed rice.
We left very satisfied, but not overly full.
The staff were friendly, we had a new staff member who got our entree order wrong but another wait staff had that fixed asap, One thing I expect from Wait staff is a simple smile and to be efficient, so one small hiccup did not ruin our night.
You would be wise to book ahead as each time we have been there we have watched people being turned away, as it always seems to be busy, which is another reason why we trust Phe Yen.
We will definately be returning, maybe without our friends, we will take them to a place we can hear each other speak.
