I went to Graze three times, and I must say, there's a reason I keep going back. The staff was very competent (especially the servers). They really knew what they were talking about and were able to tell me what ingredients were in the menu (and for a menu that's changing with the seasons, that's very impressive). The servers were also very attentive and patient, and I had a positive experience all around. Though the wait was quite long every time (without the option to set a reservation), I would say it was worth the wait each time.
Every time I have gone, I always get the bone marrow and my boyfriend gets the cheese curds. The bone marrow at Graze is definitely the best I've had in Madison. I also love the mussels on the menu with the side of bread they offer. With the changing menu, I'm always excited to try new things. Although on the slightly expensive side, definitely worth it. I recommend going on a date or taking your parents when they visit to really impress them. I've gone for both brunch and dinner, and dinner was a slightly better experience, but I do recommend trying both.
