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!

    I visited this place again as my experience there was so pleasant last week. I ordered the same things(the ones I ordered last week) to introduce the amazing dishes to my family, however, it was really disappointing this time. Ordered the risotto and Tokyo Chicken, and the rice wasn't cooked well. The first time when I tried risotto, the rice was cooked really well and very smooth. The second time, it was hard(probably, not cooked well enough?) . And the shrimps were not cooked enough(tasted fishy too). Thankfully, they made a new one to us, but it was still disappointing as the rice part got saltier. The tokyo chicken was really disappointing as well. The chicken part was good, however, the rice wasn't done right. I really loved the buttery taste and crunch texture of the rice(for the first visit). However, the second time, the rice was really sticky(sticking to my teeth), and wasn't the same as the first time. As a person with asian background, I could tell the rice was cooked with too much water, and it was not cooked properly. We informed the server about this, but nothing was done on their end to fix this. We also ordered the food to be out at the same time, however, all three came out at a different time. Anyway, I would like to give it another try as I love the ambience there(I have visited there four times, loved it for the first three visits), but after this experience, I don't know if I can recommend this place to anybody else anymore.

    UndefinedResponded 2 days agoHello Annah, Thank you for your feedback. We are glad that you fully enjoyed your previous three visits and it is unfortunate that this time resulted in a less than stellar experience. We have addressed your concerns with our team and can ensure you that we take all feedback to heart. Thank you again and we do hope you can come back again and visit us.

    First time at Undefined, and had an absolutely amazing dining experience. From their signature cocktails through to dessert, everything was a taste treat. Don't miss the mussels a la snob... Best mussels I've had EVER! If you're into chocolate, the flourless chocolate torte is an absolute must! For the quality of the experience, very fairly priced... cannot wait to return!

    What an amazing restaurant! The ambiance is really cool and trendy. We went for Father’s Day brunch with our 2 teenage girls and everyone loved it. The blackberry lemon mimosa is not to be missed. They hand middle the berries. So good. It’s family run and the owner/chef came over to check on us and had a fun conversation. Our waiter is his son and was so friendly and funny. The s’mores French toast was a huge hit with the girls. My boyfriend had the Fried chicken with biscuits and gravy and he really enjoyed it. I had the pork belly Benny. It was delicious. Everything was nicely plated as well. It was a great experience! We will be back for dinner!

    Ryan the waiter made our evening. He conversed in Italian with my friend and shared his background with us. He was very conversant with the menu and specials of the day. He was busy though and didn't attend to us immediately. The restaurant was extremely noisy and the tables too close together. The lamb special was excellent and my friend enjoyed the risotto with shrimp. If it weren't so noisy and crowded, I would return.

    Booked a reservation for my 5 year anniversary and specified in the reservation that it was for an anniversary, arrived at the restaurant at my reservation time, I gave the hostess my name and saw her walk over to another server as they looked at a computer screen, their conversation looked awkward, the hostess returned and said it would be approximately 1-2 minutes before my table is ready, after 10 minutes of waiting the lady who the hostess was talking to about my reservation comes up to me and says that my table will not be ready for another 40 minutes and they will text me when it is available. It is obvious they seated someone at my reserved table!!! They did not try to accommodate at all, and as for the text or call when the table became available they NEVER contacted me!!!! Leaving me with no where to go at 10pm for my 5 year anniversary…. I ended up going to Ruggatino on Locke st who were great and accommodated me last minute keeping their restaurant open past closing to provide a great anniversary for my fiancée and myself. UNDEFINED was very unprofessional, and obviously did not care about ruining my anniversary. I advise anyone who is planning a special occasion to choose a different restaurant and I will be telling everyone I know how UNDEFINED IS TERRIBLE!!!!

    It was great I love taking my girlfriends out here for good food and an opportunity to catch up! The food felt like it took a while to come out (it was over 40 min but we were pretty hungry before coming) but it was amazing like always when it did arrive. The apple salad with shrimp is perfect for a filling meal that’s not heavy on meat. And the UD burger is my ultimate favourite I recommend these to anyone. The out door seating is very nice definitely a gem in Hamilton:)
