Whole dining room repast environment is very satisfactory, elegant decoration and comfortable atmosphere is very suitable for dining, the taste of the restaurant made fries to make people feel addictive, the more you have, the more you want because it's really delicious, after cooking in the oven medium-rare steak taste is very fresh, the flavor of duck leg although is not very rich but once with special spicy sauce will become very delicious, Salmon meat is very fresh, it's sauce filled with passion fruit, although it tastes sour but it can take the fishiness out of the salmon and perfectly integrated into the taste of salmon, fly in the ointment is I more hope to use the smoked salmon, as for Hamburg, black truffle collocation makes whole beef Hamburg become more delicious, its flavor is illegal and worth trying. All in all it's a very delicious restaurant.

Proof is a restaurant that is on the ground floor of the Delta Waterloo hotel. I typically wait until I am done staying at a hotel to rate both it and the hotel restaurant that I tend to frequent regularly. However, I'll break this cycle seeing that I have one more visit left. This Delta does not have lounge access for gold and platinum elite members. Instead, you get a voucher a day towards the breakfast buffet. It includes your choice of coffee, tea, or juice. The buffet alone is $20 a person. I am a guest at this hotel for nine nights. Getting roughly $200 for breakfast for free is pretty good. I missed breakfast one morning due to fasting for bloodwork. If you don't use your voucher, you can ask the frontdesk staff to comp you in reward points, which is 750 points per voucher. The breakfast buffet is consistent. You have both hot and cold items. After a few days, they become predictable, except for the chef's special. It changes every day, which has saved my tastebuds. They range from sausage sliders on bagels to French toast stuffed with berries. Do the chef's special. Each one was delicious. The scrambled eggs, bacon, pork sausage, turkey sausage, and hashbrowns are the main hot item staples. You can change them up so you don't go insane. I never did cereal, mainly because there weren't any lactose-free milk options. There was also a waffle maker, and a decent selection of muffins and croissants. I decided to give steel oats a try one morning. It was pretty good when you add toasted pumpkin seeds and granola on top. The servers have been great and attentive. Two stand out, as they immediately recognized me as the guest who has all these breakfast vouchers. This morning, one of them asked me how I had slept last night. It was thoughtful of her. One older server confused me one morning. I gave her the voucher and she thanked me for my loyalty. Five minutes later, she asked if I would be charging the bill to my room. Nope. She then asked if I was paying by cash. Nope. I finally had to say that she took my voucher from me. It wasn't even a particularly busy morning! The best part of Proof, besides the fact that it's not crazy busy at 8:45 am, is that there is a problem-of-the-week on the blackboard. It's a math problem. This math minor loved it, which explains why this restaurant is called Proof. The interior is relaxed and nice. I never did lunch or dinner. Perhaps when it's winter and I don't feel like leaving the hotel, I'll give it a try. I recommend if you are a Marriott gold or platinum member to enjoy the breakfast buffet here. Otherwise, try it once and then try other eateries for breakfast, to change things up. (256)

More higher end restaurant than what students are used at around the campus, reflected by the nicer ambiance, higher meal price tags, and the generally older crowd. We got reservation for 8 on a Friday night and were promptly seated when we arrived. I noticed that the place had a really nice vibe and is certainly what you would expect from a restaurant located at the newly built Delta hotel. The decor was nice and modern and you can tell they spent a lot in the furniture, tables, and cutleries. I noticed that even though they claimed to be a Canadian restaurant, a good chuck of their menu featured Asian cuisine, such as Peking Duck, which was kind of weird. Most of the main dishes are around $20 each, appetizers above $10, and even the desserts are $10. I ordered their signature burger and it was pretty good, greasy but also really juicy, definitely better than a lot of places. I skipped out on the appetizers and desserts while some of my friends got them, and it seemed that the portions are super tiny and it's definitely not worth the $10+ price tag. Even though the place wasn't crowded at all for a Friday night, I felt that the servers didn't really pay attention to us very much, probably because we were students. Overall, my group unanimously agreed that we won't come back again because the place is too fancy (expensive) for student budget, food was overall kinda meh, and it's super far from campus given that you have to walk quite a long distance from the neariest bus stop

We went to Proof for breakfast (actually brunch) after staying overnight at the Delta and having some vouchers to redeem. What a beautiful space and delicious food! We made it just in time for brunch, which starts at 10:00am on the weekends, and includes a different menu than the breakfast menu. All of the options looked amazing and I was pleasantly surprised by how many vegetarian options there were! We were even given some complimentary blueberry scones with butter and jam while we waited. I went with the rancheros, which were presented beautifully and super delicious. They were full of flavor! I'm not used to this level of excellence when getting the next-day hotel breakfast so it was an amazing experience all around. Definitely worth a visit, especially if you're staying at the Delta! They're open for all meals too, so I imagine that late-night dinner and cocktails would be just as amazing!

Went on a Saturday for brunch. Restaurant was spacious, clean, & quiet. Food was pretty good but was served quite slow. Service was good. Restaurant is located in Delta Hotel and you must walk through the hotel entrance doors to go into restaurant.

2nd time here and it's still absolutely amazing! I originally had a reservation for a table on the patio and got a call from the restaurant warning me that it was cold and windy and was luckily able to relocate inside. Super friendly and knowledgeable staff who were attentive and were able to recommend the best dishes! I personally really enjoyed the Cappelletti (really good cheese and seafood flavour and was rich but I didn't find it overly rich). Beef Carpaccio is a classic here (I don't eat beef but my tablemate really enjoyed it) The chocolate ganache was surprisingly smooth! I'm usually not a fan but this one wasn't as grainy or chunky as other ones that I've tried (very rich but if you're a big chocolate fan then this is for you). Cheesecake mousse was a nice, lighter version of a cheesecake (nice mix of richness and fruitiness). Pink sapphire cocktail was a bit disappointing, came in a mug instead of a nice glass and didn't taste the best. Grilled calamari was what I expected (not bad, not amazing). Pan seared duck breast was a bit too chewy. Overall amazing experience! Their patio seating is tented, tarped and heated so even though I moved inside, I don't think eating outside would've been too bad (even though it is Winter).

Came here with my boyfriend and loved the ambiance of the place. There were amazing options we both really wanted to try, and ended up getting the tacos for apps, rose pasta and the veg burger, then got the mousse dessert. It was all amazing! The seafood rose pasta was so worth it and would def get it again. It was great service but we ended up waiting a really long time for drinks and a beer because of the volume/time.

I went to the Proof restaurant on Thanksgiving Day. The food was very good. I myself got the burger with the double smoked bacon and it was excellent. I got a taste of the turkey special and it was also nicely done. My teenager got the Peking Duck and absolutely devoured it. The thrice-cooked fries are probably my favourite, which feels a bit silly, but they were so good! Also, the service was attentive, but not TOO attentive -- a good balance. The decor was high quality and if I lived nearby I could see hitting the restaurant's bar now and again. Finally, the prices here feel a touch too high, but it's in a hotel so I suppose it's to be expected.

I've tried their dinner menu many times from ordering room service during my stay at the Delta. There's something about their fries that I really like, although their fries aren't actually the best (I think I like the herbs/spices that are used). Today, 3 friends and I came here for their brunch and we actually sat down at the restaurant. Walking in, I really enjoyed the ambiance. We ordered: 1. Good Choices: two poached eggs, buttermilk corn waffle, dinosaur kale, sauté onions, applewood smoked bacon, breakfast link sausage, maple bourbon bbq sauce - 2 of us ordered this dish. The quality of the poached eggs was very inconsistent. My friend's egg yolks were still runny, whereas mine were over cooked. The kale + onions were mixed together and I found that part a bit too salty.. The sausage and waffles were average. Bacon normally isn't my favourite but I'd say it was what I liked the most out of everything. 2. Dreams of Montreal: Citrus tea cured Coho salmon, herring and caper potato salad, soft boiled egg, mini Montreal bagels 3. Breakfast Burger: Norwich County beef, smoked cheddar, peameal bacon, poached egg, Hollandaise, house baked milk bun, thrice cooked frites - Loaded burger.. will definitely fill your empty stomach. It came with a choice of salad or fries as the side. The burger (even the buns) looked a little greasy, but overall a good meal if you prefer something heavier. Almost forgot to mention that we were a bit disappointed with their service.. our server did not appear friendly or approachable at all. We often felt ignored when trying to ask for things. But I believe this is likely just a one-time exception, as the other servers seemed more welcoming to their customers.

This is my second visit to Proof, located in the lobby of the Delta hotel. The food does not disappoint! I ordered the lamb burger and it was a big juicy patty, with a side of fries or the Norfolk Greens salad. The salad was a great healthy choice - loved the sunflower seeds and the dressing is tangy yet delicious. I would highly recommend this as a date spot or get together with friends!

I am not sure why it's labelled as a Canadian restaurant since most of the food is from Asian cuisines. To be honest it's one of the worst and most overpriced dinners I have ever had in Waterloo. A drink, an appetizer, two main courses and two desserts cost me about $140 in total. If they were worth it, I wouldn't mind, but their food was just average at best. We had tuna tatami and green curry. The tuna tatami is simply topped with a pan fried tuna steak and very salty soy sauce on the rice. My friend's green curry was just like any stirred-fried Indonesian curry in any of the other Asian fast food restaurants. The selection and the taste of desserts were not impressive either. I had certain expectation of the quality of Delta's restaurant based on other restaurants in this range but was left disappointed.

Accessed through the lobby of the Delta Waterloo, Proof Kitchen and Lounge is a nice dinner option in the area. We appreciated that the staff seemed to take extra precautions for allergy situation and when I told them that I am a Celiac, they demonstrated knowing how to handle their side of things. Congenial staff and well presented locally sourced ingredients; flavours, textures and colours were on point. Breakfast was a lower standard than dinner, more like the typical options found at Marriott/Delta properties.

Really liked this place! My antioxidant salad and dulce de leche cheesecake were both good, but the real highlight was my papardelle with shrimp, double smoked bacon, oyster mushrooms, kale, and lemon ricotta. The pasta was freshly made (I don't know this for sure, but if it's not you could have fooled me!) and the flavours were fantastic! The atmosphere was chic and modern, although I found the restaurant unusually loud, making it hard to carry out a conversation. A+ service too - our waitress was very friendly and helpful!
