This should accept "go in" and "come in" as well as "enter".

Why was "I don't want to come in" not accepted?

"Xiang" is "would like to," "yao" is "want." Therefore, this sentence should be "I would not like to enter."

I never hear that at a restaurant!

The hover hint only says "inside" so this is problematic. It would be entirely reasonable in English to say: "I don't want inside (as opposed to outside) when offered a choice at a restaurant. If 进 is a verb meaning "to enter" or "to go inside" then the hover hint should say so. There is no word in the sentence that indicates movement, like going.
