I had always thought a noun or a gerund should come after "How about", like "How about that place?" or "How about going there?"
However, today I heard someone (a non-native speaker of English) say "How about over there?" She was suggesting having a meetng in a room that was "over there".
Is this sentence correct? I'm not sure what part of speech "over there" is, but can it be placed after "How about"?
Yes, it's very normal. "Over there" is an adverbial of place.
Of course, it's not a sentence. The obvious meaning, in context, is "How about we meet in the meeting room over there?" In this case, "over there" is a reduced adjectival clause, from "the meeting room which is over there."
"How about" can be followed by almost anything in the right context.
