It is right by the beach, ideal for my daughter to play while we watch her. The steamed crabs, oysters sashimi, lobster were all memorable and very fresh. More expensive than other local eateries, but still considered rather cheap. Our server N T Duong is a gem, she was smiley and could understand english well. The rest of the staff was not as attentive.

By far, the best place to dine along the beach

We ate out on the terrace overlooking the beach and had a nice breeze. The staff were attentive and pleasant. Our drinks were cold and the food was good. I would recommend for lunch as it is quieter and more chance to sit out on the beach terrace.

Da Nang was not much to look at or walk through. On our visit, it seemed like it was mostly a city starting to develop and turn itself into the Vietnam version of a Miami, or Rio. But not nearly as exciting.
But Blue Whale was a site worth visiting. We found it as we walked along the beach. Tremendously good food. Cheap. Nice outdoor dining on a pretty nice beach.
I felt it was worth the visit.
Only downside maybe is a huge number of tour groups during the lunch hour, mostly from China.
But that is par for the course in Asia travel these days.

Having lunch there, order crab with bread. Bread didnt come untill our food finished. Asked for discount, they just gave us 15.000 vnd discount (our tottal bill was 700.000)
No one say sorry. Specially the manager. He just stormed out ignoring us.

Came here by chance. Nice food not exceptional but good. Reasonable price. Service was good. Nice view out to the beach and sea. Not over busy when we went. Waitress was very good and informative. Would use again.
