I have to say I was very impressed with my most recent experience at The Keg!
I ordered "The Keg Burger" and was amazed at home much their quality has increased over the last time I had the burger. The meat wasn't dry or salty; something that I have experienced at other burger places. The bun was also nicely toasted and not overly crispy, or soft (if that makes sense). In summary I'd say it was the best burger I've ever had anywhere.
I also had a Mango Mojito to drink and was pleasantly surprised with that as well, the drink had a strong taste of alcohol, something I don't usually experience when I have mixed drinks from restaurants.
The service was also amazing and top notch considering how busy they were for a weeknight. Our server and the kitchen manager both came around to make sure we were satisfied with our meals, a nice touch since service at The Keg can be spotty at some times.
All in all, definitely give their burger a try if you're looking for a little more of a formal burger eating experience!
