Best beach bars in Dubai?

Two completely different ambiance but you should try both  Barasti and  The Jetty Lounge in the One & Only. 

They are both located close by on Al Sufouh next to the Marina. 

Barasti is a vibrant, buzzing place with a younger crowd and Jetty Lounge is an upscale beach lounge with a beautiful setting.

Barasti (within Le Meridian Hotel) near Dubai Marina has been voted best bar in Dubai for years. It has 2 different atmospheres: the first floor has a restaurant, tables and bar, while the ground floor, right by the beach, is where most of the action is at! There's beach loungers and great areas to sit outdoors and some days there's also salsa dancing classes taking place. If you're going to check out one beach bar in Dubai only, this one should be it! 

One of my favourite beach bars in Dubai is La Veranda at the Jumeirah Beach Road

Good food, great drinks, a lovely views of the Burj Al Arab and the setting sun.

Atlantis, The Palm is a great place to enjoy the beach and nightlife at the same time. Barasti is another great beach bar catering to a lot of the expats living in the area. 360 Degrees- Dubai- UAE is a unique bar on an peninsula off of the main coast. Great views of Burj Al Arab!

loads of places to eat along The Walk - wide range of styles & prices, nice to wander along & make your choice, & great for people watching!
