Meaning of "でも" in "食事でもどうですか？"

Question

I've found this sentence on alc.co.jp

食事でもどうですか

and I am puzzled as to meaning this でも conveys. How does it differ from

食事はどうですか

This would be my first choice but which, according to Google, is used less often?

Answer 1

This でも is used to mean "〜 or something", usually in regards to suggestions. It leaves room for other options.

• 食事でもどうですか　→　How about something to eat (or something else)?
• お茶にでもいかない？　→　Would you like to go out for tea maybe?
