For me, the gravy is what separates a good Mee Rebus from a not-so-good one. And personally, I find Kampong Glam Cafe's very satisfying. To start with, it isn't too starchy and there're detectable dimensions of flavours in it. Within the potato-based gravy, sweet and savoury co-exist happily. After which, with a squeeze of fresh lime, sour joins in the party.
PS. My tastebuds concur that Mee Rebus without lime is like a face without a smile.
