Lemna of The Alchemist is a cafe near the Hong Kong Museum in Tsim Sha Tsui that serves brunch and meals. Its menu includes salads, truffle pasta, crab quesadilla, and paper-wrapped sea bass. Orders are placed only through a QR code, and the seating is spacious with tables not pushed together, so the air conditioning runs strong. A 10% service charge is added to the bill.
