KaiohDon @ARC is a sushi restaurant at #02-43A Alexandra Retail Centre on Alexandra Road in Bukit Merah, Singapore, holding a strong 4.8 Google rating. Good sushi is judged first by the rice, not the fish on top: it should be served at body temperature, lightly seasoned with vinegar, and packed loosely enough to fall apart on the first bite. Freshness shows in turnover, so busy counters near offices and shops are often the safest bet, and a short menu that follows the market usually beats a long fixed one. At the counter, regulars watch the chef's knife work, ask what arrived that morning, and dip pieces fish-side down in soy, lightly, so the seasoning still comes through. Perched on the second floor of ARC, this is a handy stop for anyone working or shopping around Bukit Merah who wants sushi done properly.
