Unusual Tree

Do you know what tree is this? We have seen this at Cocolime restaurant at Subic when we had our lunch there last time. We were actually seated on the garden area opposite this tree and we've noticed that there were lots of customers who approached the area and have a closer look of the tree. Probably, they were curious same like us. We even overheard an old man saying that he wanted to have the same tree in his yard. Interesting, huh?
