The Hilton Tashkent is a fine hotel, very modern and clean, but it is really very big. It is inside the parking security for the city park across the street which I suppose makes it more secure, but it also creates traffic jams around the hotel as taxis compete with park visitors. (Traffic jams around hotels, airports, and train stations are very common in Uzbekistan, btw).
The breakfast was excellent, the rooftop restaurant was pretty good, in that international/cosmopolitan shopping culture sort of way.
