Rasa Penang is a dreadful eatery. Sugar, salt, fat. Deep-fried this, syrupy that.
The menu is ridiculous - nowhere could cook that many dishes well! And as far as I can tell, they don't cook any of them well.
Good malaysian - C&R or something (Rupert's Court, Soho, and there's one in Bayswater). "Bugis Street" near Gloucester Rd tube is great, and authentic - properly authentic, hardly any gwailos.
It services travellers from Singapore and Malaysia (the hotel is owned by a Singaporean).
Rasa Penang - no good food, rude and pushy service, high prices, questionable quality.
