I came here with my girls, it was 5 of us and we came for brunch. The food was delicious and we also ordered some champagne, shots and drinks. We spent a lot of time at our brunch, the vibes of this place are very comforting and the music was upbeat. Everything was really good, will definitely be going back and recommending to my friends and family!

What a wonderful experience. My wife, daughter and I stopped in for an early lunch. The staff was very attentive. Our server Michael was excellent. Our food was wonderful. We sat outside and what a great atmosphere. Highly recommend!

I have visited three times since the remodel and I have to say, every aspect of this place has improved to 5 stars. The atmosphere they have created is beautiful in the daytime and at night. Try the salmon, you won’t be disappointed! Kudos to Alex and to the new Chef! I highly recommend this place for any occasion.
