UnDefined has been changing the way people think about dining out in Hamilton. Voted one of Hamilton's best all-around restaurants for 2021, 2022, 2023, we are making a big impact on King William Street. With an evolving, seasonal and whimsical approach, our passion is what drives us every day. We strive to push the limits, and for our team, it is just what we love to do. We cook from scratch because that is just the way it should be. We love to challenge the way we all think about dining out.

We believe that there is no reason to put yourself in a box when going out with friends, so we do not do that here. Whether it is a night out with friends, an intimate dinner for two, or just something extraordinary, We are not afraid to take the familiar and turn it into something memorable. If it tastes good, we will put it on a plate, in a glass, or whatever. Our mantra is as simple as eat, drink, and enjoy!

    What an amazing experience! The New Years tasting menu was beyond our expectations. We will definitely be back next year. The servers worked so well together. Each course was amazing. Looking forward to our next visit.

    Came here previously for dinner, and had a wonderful experience & meal. Brunch today was a different story - the food concepts (the egg Benny’s in particular) sounded fantastic, but didn’t translate onto the plate. Fried chicken was way over done & bone marrow benny turned the bread into a wet mess. Won’t be back for brunch

    Loved everything about this little gem. We celebrated my daughter’s 18th Birthday and it was absolutely perfect. From the food to the service it was a 10! Highly recommend!

    The mussels were excellent the cocktails delicious Main course was the scallops and risotto I found the risotto a bit greasy but my husband thought it was perfect so there you go different tastebuds Only criticism is the menu the writing is so small you can’t read it bring a magnifying glass Our server was very knowledgeable and personable, we got our food very quickly Would recommend this restaurant to our friends
