Good ambiance and nice jazz music. Drinks are nice but might have to come really late as it was rather empty at 10pm.

The Harrison is a New York prohibition themed speakeasy tucked behind the Nicky NY sushi. To enter, you must walk through the restaurant and a server will take you behind the wine cellar and a "Time Machine". It was a bit funny seeing another country's interpretation of "American culture" but I think Harrison nailed it - from the New York newspaper menus to the classy interior to the expertly made cocktails. I could not decide on the cocktail menu, so the bartender asked me what my preferences were. She whipped up a mint banana drink and it was SO AMAZINGLY GOOD. Like one of the best cocktails of my life. AND it was only $6!! (Granted, all the cocktails in Buenos Aires are $6 USD) During my visit to Buenos Aires I also tried two of the "world's top 50" bars: Tres Monos and Floreria Atlantico. Honestly, I think Harrison has them both beat in terms of ambiance and beverage. Wonderful experience and I will definitely come back the next time I'm in town.

Great drinks (very cool and unusual "glasses"!) and awesome ambience. A must-see in BA behind Nicki Sushi.

Really cool speakeasy on par with speakeasy in the USA. Will recommend, usually they require you to eat before you are able to go to the speakeasy.

So it's inside Nicky NY Sushi. We didn't have reservations and we didn't eat there either. We walked up and said we want in to Harrison's and they laughed at us. We were given a business card. And told make a reservation and come eat sushi. Lol!!!! Then the truth came out "we leave tomorrow, we're a crew with (bleep) airline and we were told you guys are legit." The guy looked at us and said hmmm please hold, checked with someone, and came back and said OK come this way. He led us through the sushi restaurant, then a hallway then we stopped in between a couple doors, the following door looked straight out of a submarine. We stopped in what looked like a foyer. We soon found out it was a foyer between two worlds the current time in Palermo, and The Harrison, New York 1930's. We walk in to the past to Nicky Harrison's speakeasy, where it's dimly lit. A charming waiter with the coolest mustache recommends a few libations and we transcend to a prohibition era were only a few know where to find booze.

Very refine and classic spot. The cocktails were great and the vibe was very good. Excellent service as well.

There's nothing better than grabbing a creative and delicious cocktail. What makes it even better, is when you can walk up to the bar and have a very cool pair of bartenders give you suggestions on some of their favorites, or on drinks that fit your taste in booze. The Harrison tops off the list, with its true "secret" entrance through the restaurant in front. The staff walk you through and give you a brief history on who Harrison was, and how and why he is infamous (not gonna ruin it, you should just go yourself). From there, you can sit at a table, or at the bar. This was the best option, since many bars don't have seating in BS AS. The creative menu gives you many options to choose from, and the bartenders will also give you a hand. This is definitely a great place for a date, or an intimate conversation. Sure, come with a group, but it's not a loud place.

I have traveled the world for work and when I go somewhere I'm always looking for a cool probation era styled bar and this place wins for Argentina I was impressed and I go to a lot ! If you want to get right to Buisiness and get some proper cocktails by mixologist go here !!!
