Contemporary Canadian
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, 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!

    Food was excellent. Seating was uncomfortable for one guest due to the narrow bench space created by a jutted out wall. We were unable to be accommodated in a more appropriate spot. The server was pleasant but unskilled and constantly coming back to the table to interrupt. The plates were cleared before everyone at the table were finished eating and we were informed of our time limit and the need to have the table for the next reservation long before the time and the entire experience seemed rushed. It is nice to have reasonably quick service but not good to feel pressure.

    We sat at the bar so a bit of a different experience. The bartender was friendly and accommodating however once the restaurant began to pick up he was not as attentive because he was non-stop making drinks. So while he was doing his job I feel like maybe the restaurant manager or like a head waitress could have picked up the slack in terms of clearing our plates or bringing the bill. It felt like we waited a long time for this. The food was quite good. My husband ordered the wagyu but they were sold out, odd as it was early in the evening and since we were sitting next to the kitchen we could hear the orders being called out and heard the wagyu several times. So we both ordered the lamb hibachi which was served on a literal charcoal hibachi. Fantastic presentation. While they provided a separate knife for the dish, it still wasn’t sharp enough so I had to fight to cut my food, and since we were sitting at the bar, which was marble, my plate kept sliding. So better or sharper knives would have helped. The sides were some greens and grilled squash. Both required salt but overall I enjoyed my meal. I would go again.

    This was our first visit to Undefined and we weren’t disappointed. The food was excellent. We had the Wagyu Steak, Hanger steak, pork belly and the lamb hibachi. They were all cooked to perfection, delicious and the presentation was outstanding. Compliments to chef Matt! Our server Kate knew the menu well and made great recommendations. Service was timed perfectly. We also had four desserts all of which were fantastic! All of the staff, including Mike and Ryan were friendly and attentive! Definitely worth the drive from Toronto! We will be back!

    The indoor seating is very loud and crowded. Outdoor seating is much nicer, except there is a possibility to rain. The service is extremely slow. Waited one hour before served any food. Recommend to order an appetizer/snack besides the main, so you are not too hungry when main shows up.

    We were excited to come celebrate a birthday based on online reviews and the menu. We enjoyed our appetizers very much. However, our mains were a bit too salty for our taste - that being said, the food was still good and flavourful. The presentation itself was fantastic. Our server was friendly and we enjoyed her very much. The host was also very accommodating in giving us a patio seat since the weather was so nice outside.
