I booked a Fri and Sat Night stay at the Peninsula for my wife and my 1st wedding Anniversary. To simply put it, the Peninsula exceeded our expectations of luxury, service, and relaxation. Check-in was fine, it is a nice touch for the front desk attendant to peronally escort you to your room, give you a brief tour, and inquire of any other needs. The Deluxe king we booked was very clean, spacious, and comfortable. The kingsize bed was very comfortable with plenty of pillows and soft comforter.
The bathroom was very large, marble everything, the highlight is the tv/radio controls for use while in the bathtub. The deep soaking tub and seperate shower have excellent water pressure and space for two.
On Saturday night we went to the lobby for the Jazz at the Pen. The jazz quartet was very good, able to read and play off of the crowd.
The spa and finess center were top notch. The pool is very nice and sun filled, there is an outdoor sundeck, but it can get quite windy 20 floors up.
Room service, housekeeping, and the front desk staff are very efficient and accomodating.
Our weekend at the Peninsula Hotel was arguably the best we have ever had, aside from our honeymoon.

Great 5 nights at The Peninsular where the service was supreme, the room great, the location perfect and the food delightful.
Ate the mad 15 course tasting menu at Avenues - little bit too much food for our delicate UK stomachs though the locals seemed to fare better!
Great room service food and excellent staff. Concierges were superb and really did know where to go and what was what in terms of tours, restaurants and places to visit...
Spa worked a treat - great views and great massage - nothing too much trouble.

You come into the hotel and come up one floor to the main lobby to register. The rooms are large and very well decorated with mood lights even in the bath room. The shower was one of the best I've had and the hot water comes on right away, with excellent pressure.
The health club is well situated in the top floor with and indoor pool. The bed was outstanding, with very comfortable down comforters.
Meals are a little on the high side, but very well presented, but with small portions. Meals are served in a beautiful lobby and a delightful place to hold a business lunch. Service in the whole hotel was excellent and lived up to the reputation of the Peninsular. It is well located opposite Saks 5th Ave, and half a block from the main shopping street.

My wife and I spent 3 wonderful days at the Pen Chicago. It was our anniversary so we received a double upgrade (one for Amex FH&R and one for the anniversary). We booked a junior suite so we ended up in a deluxe suite.

The room was very fresh and new looking. The furniture was in excellent condition, electronics were of the highest standard (Ipod ports at TV's, memory card ports at TV's, the usual Peninsula bedside console, DVD players and a TV in the bathroom). Kudos for the free wireless! The bed was comfortable with soft sheets, the bathroom was large with a big shower plus a separate soaking tub and the sitting area was spacious. The soundproofing in our room was excellent and the blackout curtains made for a great sleeping environment.

Service was top-notch. The bellmen were fast and friendly. The front desk staff accompanied us to our room and were exceedingly gracious. Housekeeping was thorough yet almost invisible. The concierge made good recommendations about dining and places to see. The hotel arranged airport transportation which was flawless.

Dining: Shanghai Terrace is exceptional for high end Chinese, I cannot adequately praise this place. Be warned it is pricey but worth it. Room service is both prompt and quite good albeit very costly. Pierrot the French cafe is ok and a quick place to grab lunch or breakfast.

The Bar is always crowded and if I had one complaint we had a sour waitress the one night we went down who shorted me on my scotch as I received the "last shot" in the bottle. That was not an excuse for a short drink.

On our anniversary the hotel sent chocolate covered strawberries and a bottle of French Champagne which was unexpected and very nice. This hotel delivered a product and service at an exceptional level for the United States. As a very frequent traveler this hotel is among the best I have seen in a US city. Yes, it is very pricey but they deliver a top notch experience with great rooms and great service. The location cannot be beat either.
