でも

About

でも can be attached to a noun to express "noun or (something similar)". This pattern sounds polite and is commonly used when inviting someone to do something, or when offering someone something.

E.g. コーヒーでも行いきませんか。
"Would you like to go for coffee (or something like that)."

E.g. お茶ちゃでも飲のみますか。
"Would you like to drink some tea (or something similar)?"

This use of でも "softens" requests and makes the speaker sound open to options.
