Input: Came here for a friends birthday and was impressed! The service was wonderful! Everyone is so friendly and helpful, the chef even came over and said hi. I ordered the duck, it was delicious, very flavorful! The only complaint I had was that it was just duck, no side. Although it was good it was a little weird to eat just duck for dinner.
