The St. Regis
Architect: Trowbridge & Livingston, Sloan & Robertson (expansion)
Midtown East
This Forbes 5-star hotel on 5th Ave. was built under the direction of John Jacob Astor IV in the early 1900s and has maintained its original neo-classical architecture throughout the past century. The top of the St. Regis houses a 14,000 sq ft ballroom and sits atop the Presidential Suite, but the $15,000 per night price tag may have to wait for those with stacks on deck.
