"tl;dr Worth a stop when you 're in Kingston. Good, but not perfect burgers, great service, and fast. I really enjoyed my cheeseburger from The Grub Hut. It was very good, although I would 've made some different choices about how it was built. I 'm not a fan of the red onions and green leaf lettuce, but I understand that those are considered premium ingredients these days. Give me iceberg lettuce and yellow onions (preferably diced) every time. The excellent patty was under-seasoned and the burger would 've benefited from twice as much mayonnaise. With all that said, I was very happy with my lunch and will visit every single time I 'm hungry and in Kingston. I loved it. Service was much quicker than I expected. I received my very large order within 10 minutes. I expected to be there 20-30 minutes. Prices are fair. I 'd never call them cheap, but they 're hardly expensive. Considering the nice touches, like homemade nacho cheese, I found the Grub Hut to be a real value. Definitely recommended."
