Cheap and tasty tempura on Japanese rice — what’s not to like? But our biggest bugbear about most tendon joints (we're looking at you, Ginza Tendon Itsuki) in Singapore is that they are grease traps, and you leave smelling like you spent the last hour rolling on a bed of you char kway. That's why we stroll into month-old Tenjin, the Les Amis Group’s latest casual offering, with unwashed hair. Why bother when we’d have to shampoo again immediately after our meal? But, lo, there’s practically no pong of oil within the light-filled restaurant at Shaw Centre. Because the kitchen — visible through a small glass panel — is thoughtfully tucked within an enclosed space separate from the dining room.
