I have gone for both brunch and dinner.
The brunch service was slow, we had to ask 4 different times for coffee! Once the food did arrive, was very pleased. It was the same quality taste and ingredients that I've come to expect from Vivace after going for dinner.
The dinner is amazing! I've had nothing but great experiences here for dinner, even during restaurant week when its a little overwhelming. An impressive date night or special occasion place, but I go just cause I feel like it when family is in town as well.
