The restaurant didn't have big Sri Lanken crabs when we went (the waitress said each crab was less than 1kg) and she was quite insistent on us getting one of the angmoh crabs (Alaskan and Australian). Angmoh crabs are very leggy, and have v small bodies.
No Signboard does crab in 5 ways - the boring garlic ginger steamed crab, white pepper, butter, and chili (can't remember what's the 5th one, but it sounds boring). They don't have the salted egg yolk crab (which is very yummy! feel like eating it now).
I think this was the Australian snow crab, and it looked like an albino crab cos the shell was very pale.
White Pepper Crab
This is No Signboard's signature crab dish, whic is also very spicy. It's quite dry, and the sauce looks like silt (but doesn't taste grainy at all). It's an interesting change from the usual black pepper crab.
Don't care if its Singaporean or Malaysian, just as long as Msia doesn't patent it. My fave crab dish ever. It was quite spicy (for my pathetic chilli tolerance, but for everyone else it was fine) - it's very sweet and syrupy sauce.
The restaurant is very atas, even dissects out the crab. Good for people who have just done manicures and want to eat crab.
I particularly liked the drunken prawns with herbs - never had my drunken prawns this way before, and although I don't eat the herbs (the wierd roots and ginseng lookalike things), the soup tasted really nice.
