This was a totally unexpected and delightful experience. Located on the 20th floor of the Hartford Steam Boiler building, this restaurant boasts a view of Hartford, CT that is stunning! I was seated at a small table along the windows overlooking the CT River and watched the sunset. The dining room is classically appointed, the service elegant and the food... More

The food is creative, eclectic and right up any "foodie's" ally! Interesting combinations and fresh local ingredients will delight hit palate. Best service in Hartford- true fine dining. The atmosphere is sophisticated, and has an exclusive feel with an unbeatable view of the CT river. The wine list offers a great selection to fit any budget. Go here!

My date and I had dinner at ON20 on Oct 15th for Hartford restaurant week. They have a limited menu for restaurant week but the courses were well prepared and the service was very attentive. I'm looking forward to returning for the full menu soon.
