My wife and I walked into the restaurant without a reservation this evening and was told seating was full for the night. There were obvious tables available but maybe they were reserved. Ok, that's fine. We walked away and I was thinking whether we didn't get a table because we were dressed too casually or were we refused a table because of we are minorities. We recollected that there were people in jeans and t-shirt. Hmmm... Then I went to their website to see if there was availability. OpenTable.com had immediate availability all through the evening. So... Either OpenTable.com is incorrect (which has never occurred) or I was racially profiled. It's unbelievable that this is happening in NYC in 2020.
