I really think the Penang in Boston is way overrated. Instead of the hustle and bustle restaurants typical of Chinatown, they have decided to cater to the upwardly mobile. While lacking the sophistication of service, they do not lack in the ways of a monopoly.
I would never bring someone from Malaysia (or even New York) to Penang. But don't worry, there exists much better Malaysian food.
After reading an article in the paper where the author specifically traveled from New York to Boston just to eat at Anna's Taqueria, I think I will do the same and take the $20 shuttle to New York and eat a Nyonya (or even the Penang there).
Although I disagree with the consensus on this board about Penang, I have no qualms at all about endorsing Taiwan Cafe or for that matter Victoria's on Comm. Ave.
