Since the name of this local Hong Kong chain is not written in English I have no other choice than to call it "That Mango Place". There are a few of these and they are usually crowded, especially the one I went to today at lunch-time in Causeway Bay.
The menu always reminds me of that Monty Python's Flying Circus "spam" skit as everything has mango in it -- "Do you have anything with a bit less mango in it?"
Whatever I got today. Mango, mango custard, and rice balls and...mango sauce!
