Take a taxi to find this large place with a totally different feel than the other great bars of Rome. This one is very modern, with an incredible rooftop level with its own taps and grills. Unparallelled (in Italy at least) selection of European and American beers, but little to no Italian stuff. Quick, efficient and knowledgeable staff. Don’t miss this one if you’re anywhere in southern Europe.

An extremely odd place that attracts mostly young people, but the beer offered is of very high quality, you’ll have a few german and belgian specialties on top of rarer Italian ones (White Dog for example) which makes for enough stock to spend a nice evening. Very efficient service, quick and apparently happy with their job. Rather loud music, but it feels at place. They really seem to appreciate beer and you would never guess that from the outside which looks like nothing and especially not from the pseudo-modern inside which looks like everything.

Brasserie 4:20 is a brilliant place. If you are lucky to visit when Alex is around you will experience an amazing host! The venue is a decent walk from the city centre but Im sure buses stop close by. Inside is a harmonious cellar atmosphere with exposed brick and warm glow of dimmed lights. As you walk in you are welcomed by a vintage gueuze cabinet! Fantastic range of beer on tap, with a few Mikkeller brews for example. There are many bottles available and also a vintage bottle menu but expect to pay hefty for the privelidge. Also food is top notch. A must visit in Rome or anywhere in the world for that matter.

Definitely one of the best bars in the world. The beer selection is outstanding. The venue itself is a joy to pass time in. No detail has been overlooked: the draft system is simply beautiful, the lighting is dynamic and fun, the seating is varied and accomodating. The bartenders were great, very friendly and very attentive. The draft beers are relatively well priced, but some of the bottles are comical. (I saw Magic Hat #9 for over 20 euros, same for Victory Prima Pils. And what’s more, these beers are being marketed as vintage. A 2008 Prima Pils anyone? Anyone?) Another mild qualm would be that the Italian beer selection is minimal; in fact, I can’t really remember any Italian beers. The food is exquisite, particularly the desserts. I recommend with my whole heart the Tiramistout and the cheesecake. The ribs were also great. So overall this place is fantastic. You will pay for the experience, but your money will be well spent. Absolutely worldclass.

Brasserie 4:20 is pretty high end looking, pretty posh inside and complete with a sick roof deck that has Cigar City, Lost Abbey, and other American rarities on tap. Bottom floor has tons of random micro brews. Lambic vintage list is stellar with 3F 1999 Geuze and Millennium Geuze. But these are pretty expensive. Over $200 each for the bottles. Food was very good though I did not eat dinner there, just sandwiches and snacks. The only thing I dislike about 4:20 is that it is literally in the middle of nowhere in Rome. You have to walk down Via Portuense, which at night after Sunday market looks like a post zombie apocalyptic abandoned industrial wasteland. Then door after door of non existent businesses that have addresses but no shop continue to pop up until you find yourself at a black garage door panel labeled "4:20" in green, digital clock font. It’s a little creepy. Good thing about 4:20 is that it is open until 4am! So make this your last bar of the evening before probably wanting to find a cab home.

Outside the tourist area and located on the type of fast driving street where you don’t expect to find a beer bar like this one. You won’t find many typical tourists in there. This bar attracts true beer-geeks as well as local beer lovers. The simple lighten 4:20 on the outside is not too inviting. Interior is surprising, this place is actually quite classy. Medium size, sits about 100. The setting (tables, chairs, décor) is as appropriate for easting as good dinner as it is for a long night of drinking. Food is unusual for a pub, a bit pricy and consists mainly of fish and seafood dishes. You can order snacks (fries, chicken wings, etc.). About one dozen tap lines with mostly non-italian micros. Some interesting items on tap but the tap list is not the main attraction. The bottle list is the reason you go there. Again the Italian micros are under-represented, Brasserie 4:20 is mostly about imported beer. Americans, Danishes, British, Belgians, Dutch, etc. You ask for the bottle list and they give you that long, very long list with a few hundreds of a bottles. A lot of De Molen, Mikkeller, etc. But then you can ask for the second bottle list, the one called the “vintage list” that comes in a nice book. This one has the lambics and various aged and special vintage beers. All kind of old lambics, old vintages of BigFoot and others. You can order 3 Fonteinen Millenium (A LOT of them) or Isabelle Proximus at about 150 Euros a piece (ouch! over US$200). They have a few aged bottles that I personally believe should not be aged but overall this bottle list is to die for. Service is amazing and very knowledgeable. Each bottle is opened and poured as if it was a precious 3 Fonteinen Framboos. And if the owner (Alex) recognizes you as a beer geek he will open crazy bottle after crazy bottle. This guy is nuts. Alex is to Europe what Chris Lively of Ebenezer’s is to North-America. I visited the place twice. This is one of my favourite beer bar on the planet.

First of all, from the Termini Area or central Rome, we found the H bus most convenient. Nice modern place. The terrace upstairs is really great too. Great selection of beers on tap, lots of lambics. They have great festivals too. The cellar is very very impressive, and there are a lot of good deals on the menu. Alex is a great host and his staff were friendly and very competent. A great place. Wish they had a few more Italian beers.

One of the best beer bars I’ve visited. The space itself is awesome. The rooftop area is perfect for events, and the interior has got a ton of character. Lots of interesting beers on tap, especially from their Revelation Cat label. I had a West Coast IPA and the Pinot Blend on tap and they were both delicious. The bottle list is impressive, and the staff is first-class. Really happy I got to visit and meet Alex.

We made a special effort to get over to this place, it was along a dark road, at night but the neon sign was a welcome indication that we were there. Inside it was warm and friendly, we had booked and we were reserved a table right at the far end. It was a bit of a mission to get to see the beer taps to try, my Italian wasn’t up to the job really, but got there in the end. The food is reasonable and the ambiance is good, I would have prefered to be in the bar area, but we enjoyed the experience anyway.

Yes Daaamnn. It was true what I read about this place before coming here. World class in every aspect! Rare beers - international. Amazing range of some of the best in the world. Service and interior the dopest. I will return!
