Two useful comparison areas In Tsim Sha Tsui, Nathan Road and Chungking Mansions offer many quotes within one block. In Central, the Sheung Wan–Cleverly Street area and World-Wide House are the practical alternative. No counter wins every currency, so compare the direction you actually need. Capital Exchange at Alpha House, 27–33 Nathan Road, showed 4.9 from 343 Google reviews on 31 August 2026. Recent reviews liked the rates and service. Contrary reports said the 13th-floor office was hard to find, a rare-currency quote changed, or Chungking offered more. Hong Kong Forex at Shop 110 A&B, 36–44 Nathan Road, showed 4.9 from 126 reviews. WhatsApp reservations and quick replies were common positives. Its low-rated sample included two reports that a neighbouring counter paid materially more, which is exactly why the building works best as a comparison stop. Kin Shing at Shop 87 in Chungking Mansions showed 4.1 from 88 reviews. Reviewers often mentioned no commission and a useful rate; complaints included online-to-store differences, old-note issues and an expensive TWD quote. Read the board correctly If you sell foreign cash for HKD, compare the counter's “we buy” rate. Ask three offices: “For these US$1,000 notes, what exact HKD total will I receive?” Use the same amount, note condition and direction. A better headline rate for the opposite transaction tells you nothing. For uncommon currencies, reserve only after the office confirms the amount, rate and pickup time. Count the cash at the counter and keep the receipt. Hong Kong Customs maintains the Money Service Operators register; search the exact legal name and premises. USDT Hong Kong's SFC separates licensed virtual-asset platforms from applicants. Check the current licensed list and the activity offered. A Nathan Road cash desk or social-media contact is not proof of authorisation. Never send USDT to a personal wallet; establish the legal entity, HKD payout and receipt first.
