+Absolutely loved the ambiance at Savory Symphony! The roasted duck was cooked to perfection, and the staff was incredibly attentive. A must-visit for any food lover.
+What a fantastic experience! The live music perfectly complemented the gourmet dishes, creating a truly symphonic dining experience. The dessert platter is a dream!
+Savory Symphony never disappoints! Their wine selection is impressive and pairs wonderfully with their signature seafood dishes. Great spot for a romantic dinner
+I took my parents here for their anniversary, and we were all blown away by the quality of the food and service. The chef even came out to greet us!
+The brunch menu at Savory Symphony is exceptional. The eggs Benedict with homemade hollandaise is my new favorite.
+I was not impressed with the long wait times despite having a reservation. The food was decent, but not worth the hype.
+Found the menu to be quite limited and the prices too high for the quality offered. The service was slow, and the waiters seemed overwhelmed.
+Had high expectations but left disappointed. The steak was overcooked, and the music was too loud, making conversation difficult.
+Not what I expected from a place with such good reviews. The pasta was underseasoned, and the tables were too close together, lacking privacy.
+The worst dining experience in a while. The food came out at different times for everyone at our table, and my dish was cold. Will not be returning.
