While you may have seen this one on our most popular patios blog, we couldn't resist adding it here as well. Rated the best outdoor patio for more than 10 years running, Barney's Lounge and The Ceeps is an institution in Downtown London. This spacious outdoor patio is a top spot for a good time when the sun sets. For those who appreciate nightlife with style (and want to be seen), it's the perfect place to kick back and enjoy a cold beer, pitcher of sangria or their signature Frank Sinatra cocktail.
