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.

Stayed here for two nights while visiting friends who live down the street. I had grown up having tea at the Peninsula in Hong Kong and wanted to check out a Peninsula in the States. It was really just awesome. Our room was in a lovely yellow and cream decor on the 16th floor. We had a standard room so it just overlooked the Park Hyatt but you could also people watch on the Mag Mile. Speaking of which, it is just outside your door. The rooms are quiet, with the exception of the Chicago PD and FD who seem to really like their sirens at night.

Thank goodness we got a special deal on our stay because let's face it, this place is expensive, but just oh so wonderful. We ordered room service breakfast which came to $100 for two. Very yummy however, and even better with the Sunday New York Times delivered to your door.

We also had afternoon tea included in our stay and it was just lovely. Service, food, atmosphere, musicians. Almost like being in Kowloon itself.

Everyone working there was so gracious, at ease at serving and interacting with guests. No snobbishness, just pleasant, polite, attentive.

Lastly, the pool was just really neat. Up on the 21st floor with a great view, lovely poolside seating and a whirlpool. Plus, we had the place to ourselves.

Everything about this hotel is lovely without being obnoxiously so (well, ok, sending up a bellhop in an all white sailor suit with white gloves to deliver a grimy fedex package was farily silly but I'll overlook that). Had the most relaxing two day hotel stay and I'll def stay here aging if only for the assurance that a pair of fresh padded slippers, a plush robe, and the best bath towels I've ever encountered will be waiting for me. (Also really like that they have a push button system that declares your room off limits to housekeeping until you push another button that asks for them to make up the room.)
