Explanation
The だけ family: ① だけあって = "as might be expected of..."; ② だけに = "precisely because..., all the more..."; ③ だけのことはある = "it was worth it / didn't go to waste"; ④ だけ = "as much as one wants". E.g., 評判なだけあって、本当においしい.
Examples
この店は評判がいいだけあって、味もサービスも素晴らしい。
As might be expected of its reputation, this shop has great food and service.
苦労しただけのことはあって、やっと結果が出た。
All the effort was worthwhile—finally, results are showing.
Note
だけに often appears with negative/regrettable outcomes; だけあって with positive evaluation. Compare with ばかりに ("precisely because... [with bad results]").
