I never reviewed after the first time we visited Merchant & Trade, so we have been twice now...
We don't like waiting in lines, and were lucky on this Saturday afternoon to go right in. They are pretty sticklers with the dress code, so be sure to call before going and check your attire our you might get turned away.
I am so surprised to see *at time of writing this* just 3 stars for M&T. This venue is elevated, upscale, and as many have mentioned before, serve great cocktails with an amazing view.
I haven't experienced slow service here.
One particular welcomed feature of Merchant & Trade is that they don't serve $15 cocktails in a plastic glass because you're on a roof. Instead you are handed a crystal-like actual glass to enjoy your adult beverage. I'm over the age of being on a rooftop to drink bubbles out of a plastic flute. Please. Even at the W in DC overlooking the White House. No thanks.
