I was really impressed by the menu and the food, and the way that the dishes were presented and arranged, very beautifully with a lot of class. My steak was perfectly cooked and juicy with mini pearl onions and rosemary, a gorgeous dish. My partner...More

On20 used to be a wonderful restaurant, with great food, service and ambience. No, only the ambience has survived. The past 2 visits have been downright bad. I chalked up the first bad visit to just a “bad night”, but 2 strikes are all it’s...More

We’ve been here before and really liked it, when they had another chef. Tonight was one if the worst dinners of our life. The tagliatelle appetizer was a joke; one spoonful of salty pasta in the bottom of a large plate, not even cheese on...More

My husband's and I first time at this restaurant and we loved everything beside the service. The food was amazing from start to finish but the server was very slow and inattentive. We had to ask him for another round of drinks and no dessert...More

Unimpressive ... but I have to write more ... incredibly hard to find, small portions, slow service, and amazingly average food. I can't understand why anyone would take the time and effort required to visit this place

Truly enjoyed this gem of a restaurant on the 20th floor across from the XL center. Went to check out this place during Connecticut restaurant week and my wife and I got the 3 corse prefix menu. Started with Compressed Summer Melons with delectable prosciutto...More

I visited On20 for a business luncheon. I was delighted to find On20 has a gazpacho that I now dream about! I also had a wonderful chicken dish and an assortment of desserts, including a flourless chocolate cake. Great views of Hartford, but very pricey!

As of March 2017, costs are about the same. Their 3 course meal is about $36. Add to that wine (if so inclined) and tip and it's pricey but usually an experience.
