Hilton[1] Zhengzhou opened in March 2014 (Hilton announcement dated 14 March per TravelPulse; Hotel-Online press release dated 17 March 2014), and the opening release lists Yu Garden Chinese Restaurant among its venues. Exact day differs between sources, so month-level; restaurant date is inferred from hotel opening. Estimated: 2014-03 is a best estimate and 2014-03-31 is used only as a period-end sorting date, not a confirmed opening day.Henan signature dishes alongside Cantonese and Sichuan cooking at Hilton Zhengzhou.
