Update (22 July 2013): Came back for the lunch and the $30 tendon set is worth the money. It comes with a small appetiser, the same salad and a scoop of mango sorbet. The tendon bowl itself had 2 prawns, a white fish, mushrooms, pumpkin slice and long beans. The rice was warm and drizzled with just the right amount of sauce. Tea and towel is included separately.
Verdict: Great tasting, yummy tempura that's on the pricey side, but without Chef Edward, this got to satisfy my tempura urges.
