Outstanding staff
I stayed in NYC for a training for 2 nights at 70 Park. From the moment I entered I was greeted by the front desk manager, who was kind enough to offer me a bottle of wine since I missed the wine reception. 
The hotel staff were outstanding in their courtesy. This is why I would return. The room rate was reasonable (for NYC in the Spring) compared with other hotels. The location is Park Ave & 38th, need I say more? What topped off this pleasurable experience was that I left my iPad in the room. Housekeeping turned it in and Security was very helpful in sending it back to me. I was so relieved to have it returned intact.
The only experience I was very disappointed in was the restaurant. I came in on a Tues evening and not many people were there. I sat at a table in the back for about 10 min. The waitress passed by me but never stopped to give me a menu. I finally went to the bar, where I waited approx 10 min to get the bartender's attention. I didn't want to stay at the bar and wait for another drink so I ordered the meal to go to the room. The bartender handed the plates to me with covers and silverware to carry up to the room (he should have asked the hotel staff to walk it up for me). Then, I couldn't eat the tuna - it was too rare and didn't look appealing. 
I would return to the hotel in a heartbeat, but wouldn't eat at the restaurant.
