Wall projected pictures and 60s style hanging speakers abound in this very funky bar/chill out lounge. Large bar and ample space to sit, including cinema style seating along one wall. Not too pricey and a good "before club" or "after party" spot.

We got there super early (around 9PM), and the place was empty--as one expected on a Friday evening that early. To our surprise, and to our wallet's delight, 9-10Pm was happy hour that night; cocktails were 1/2 off. We both ordered long islands; usually I can't taste the alcohol in a long island, but the bartender had fixed us up with a generous amount of alcohol. Our bartender was dressed in head to toe black, including black skinny jeans, with a mop of shaggy dark hair; he floated around the bar looking more the part of a tortured artist than a bar tender, but he did fit the grungy-in-a-hip-way atmosphere. By midnight, the place was pretty packed with people. Groups of friends sat along the walls in faded yellow movie theater seats, around the bar in the center of the bar, and stood in clumps, chatting with heads cocked sideways and a drink in hand once all the seating areas had filled up. I didn't get the sense that this is a bar that gets raucous or overly crazy; the crowd was tame even when the bar filled up--this was in stark contrast to the bars we visited in Budapest. The music was good, but nothing too special. There were a few cool trap tracks dropped; luckily no dupstep or pop. Nothing really memorable though. Donau would definitely be a place to frequent if I lived in Vienna! Definitely check it out if you're in the city.

I don't have much to say about Einhorn..

Suffice it to say that my "vodka orange" did not have a drop of vodka in it. Seriously. I was SO disappointed. However, I'm giving this place 3 stars instead of 2 because the people I was with had a really good time at this place; the beers were super cheap (and even my "vodka orange" was really cheap - though too expensive for a glass of orange juice w/ice); and the bartenders were pretty cool and nice. While I initially swore off ever returning to this place, I'm thinking I'll give it one more chance, and I'll see if they can manage to not forget the liquor next time.

When you enter the bar, it's like in the movie backdraft, where the guy opens the door and a exploding fireball blasts into his face. Entering Zipp is a similar experience though, instead of the explosion, there is loud rock music and drunken singing, and instead of the fireball, an accumulation of smoke from a 1000 cigarrettes blasts into your face, instantly making you, your hair and clothes down to your underwear(no matter how many layers you wear) smell like cigarrettes, vomit and alcohol. If you think, drunk singing, getting drunk, heavy smoking, drunk dancing in close quarters and drunk conversation is not enough for a bar... there is also a "recreational" option... The Bar tenders and even sometimes the DJ are often quite open to a challenge of "dice poker" where the loser, you guessed it, has to pay for a vodkashot round, for all participants. Or you can try to play foosball against some really skillfull players.. where, if you lose without scoring at least once, have to invite the enemy team to a drink. Btw... one of the few bars, which serve the vodkashots icecold in a frozen shotglass. A fun and weird place to be... where time itself stumbles into the toilet to throw up.
