Great view of sleepy downtown Hartford. Not a ton of great places to eat in Hartford but On20 (on the 20th Floor) was as good as any. Food was very good and service for our dinner group was excellent.

The most unknown happy hour is at this premiere Hartford restaurant. Recently remodeled to more accurately represent its unique location and views, it is truly splendid! Muted colors, colored ceilings and luxurious seating bring a needed update. Happy hour requires no reservations(indeed it's usually very quiet). Antonio handles the bar well, offering excellent varied cocktails and a nice wine selection.... More

My fiancé planned a birthday dinner for me at On 20....it was terrible! Awkward atmosphere, my food came out cold and it had to be sent back. Nothing was done as a courtesy for my cold meal either! When the bill came we realized that there is a 20% service charge for front end staff, elevator use etc... We were... More

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 facility is located on the 20th floor of the Hartford Steam Boiler building. Validated parking is available on site. If you do use their parking garage, be sure to go to the third level and enter the building on the elevator level. The facility was closed for a short while to redecorate the dining areas and bar. The old... More

It was very good. The service was ok a bit slow for a not so busy Wednesday. The food was fine, went during restaurant week fixed menu no other choices - it was our anniversary would have liked more choices. Other restaurants we went to during restaurant week offer both menus.

This was an exquisitely beautiful restaurant with understated elegant decor and the dining experience was top notch! From the delicious Amuse bouche prepared by the chef to a sumptuous dessert, you could feel the passion for the meals that were prepared for you. And each dish was just as artfully plated, which really enhanced the meal. This is not a... More
