Nice Hotel for a Conference
For the past several years, I have attended a business conference at the Grand Hyatt each May. The hotel is well-situated for convenient access to most things around the city. The rooms are clean and the staff is pleasant. 
The hotel is not "incredible," but it is certainly better than most hotels that accommodate large conferences. I do not like any of the restaurants located in the hotel, which include a sports bar (with standard bar fare) and a cured meat restaurant. However, there are a variety of dining options within easy walking distance of the hotel.
