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!

    We recently had a Sunday brunch at Undefined. It was a nice experience, not more than that. Service was great, but the food not as much. The quality of the dishes was not consistent ! The burger, chicken benedict and the mushroom benedict were pretty good, but the bone marrow benedict was really disappointing. A huge bone with very little bone marrow - not very satisfying. The person who ordered it was left hungry. Also, brunch here isnt for vegeterians. The menu had only one savory dish for vegetarians, which is the mushroom benedict,but the vegetarian in our group doesn't like mushrooms. We pointed it out to the waitress and asked to substitute the bacon in the cob salad with salmon (an add-on that exists in the menu). The answer was no, and that we can get an extra egg to the salad. Needless to say, the veheterian was left hungry too... For desert we really wanted the sticky toffee pudding, but they ran out of it. We then ordered the other two deserts on the menu - both were very disappointing. The pumpkin pie creme Brule was too sweet, and the chocolate cake was too dry and dense that we could barely cut it with our forks. Overall, we had a nice time amongst ourselves but I don't think we'll come back here

    It's always a great experience when we go to Undefined. The food is great and the service is exceptional. Amanda was our server today and Dharma was our server a few weeks ago. Both are very accomplished and sweet servers.

    I ordered the Crispy Chili Squid and the CAD Prime Hanger Steak, and both dishes were outstanding in quality and flavor. The service was attentive and friendly, making the experience even better. The ambiance of the restaurant was excellent—perfect for a relaxing and enjoyable meal. Highly recommend!

    Great experience, Now I see why they have a 4.6 star rating on Google. We were skeptical at first but the experience was the best we've had in Hamilton and also the portion sizes, the food quality and quantity and the attentiveness of the wait staff was great on our visit. The menu options were pretty great as well. 100% recommend this spot and will return !! Thanks to Undefined for a great brunch experience.

    This was my first time at Undefined and everything we ordered was on point. We absolutely adored our server who was a complete blast the entire night and just added to the whole experience. Every dish we ordered was not only impeccably plated but also extremely satisfying and tasty. This is a must try.

    We have been to Undefined on many occasions for dinner and brunch. This is by far one of our favourite restaurants for a date night, going out with friends or a weekend brunch spot. The service is always top notch and the food is always beautifully plated and very thoughtful portions. One of the reasons we really like this restaurant is they change the menu. There are always new dishes to try and the cocktails are very tasty as well.
