For decades, Buffalo's Finest Hotel was the Hotel Statler on Niagara Square, which was the largest hotel in the country when it was built in 1923.
To make sure his hotel was a success, Ellsworth Statler bought Buffalo's previous most popular hotel-- the Iroquois-- and turned it into an office building. The Iroquois replaced the Hotel Richond and St James Hall, which was where President Lincoln's body laid in state while making its way back to Illinois from Washington DC after he was assassinated in 1865.
To stand in the spot where of all that Buffalo history, just head down to one of the M&T lunch time concerts. Those free concerts have been going on for 49 years now-- but had you been standing on the northernmost part of M&T Plaza-- closest to the old AM&As-- you'd have been in the Iroqouis' lobby.
It was torn down in 1940, and the small building that replaced it was the home of the BOND Men's store--- where you always got two pairs of trousers with your suits.
