Milion is considered to be one of the best night clubs to hit in Buenos Aires. It is a converted mansion in the heart of Buenos Aires, and is a popular spot among porteños as well as expats and tourists. 
The place is spread out over three floors, and takes advantage of candles to set the mood. There are a number of glass doors and partitions, separating out different areas: a bar, a lounge, a dining area. A giant sweeping staircase leads up to the upper floors, and tall ceilings lend themselves to the glamorous mansion feel. There is also an outdoor terrace and garden area, and a DJ spinning music.
You can make reservations for a private party, or just go and chill with friends. It is open Mondays to Fridays 12 pm to 2 am, Thursdays from 12 pm to 3 am, Fridays 12 pm to 4 am , Saturdays from 7:30 pm to 4 am and Sundays from 8 pm to 2 am.
Milion is located near the Galleria de Arte, but can be a little hard to find if you are on foot; there are no big signs. There is a name plate embedded into the floor on the ground at the main entrance, but in case you miss that, your taxi driver will be able to take you right there. There are no staff at the entrance to greet you, so just wander your way to a partitioned off section where you will be greeted by the staff.
It is a pretty trendy spot, so make sure you dress up at least a little bit. Jeans are acceptable, but in general the posh crowd that hangs at Milion dresses them up a little bit. It is on the pricer side as far as Buenos Aires night spots go, but is definitely worth the trip.
And if you’re worried about the prices Happy Hour starts at 7 and runs until 9!
Insider tip: During the summer silent movies and film noir are played in the outdoor patio and shed on large outdoor projection screens. Also, make sure and say hi to 
Emilio, the resident cat at Milion. He enjoys his drinks too…
Cons would be the place is usually packed, and so service can be slow. Brush up on your Spanish as well, most of the wait staff doesn’t speak English. Also the bathrooms are on the small side, and can be a little difficult to find.
Milion is located at Parana 1048 in Buenos Aires. The phone number is +541 1 4815 9925.
