Will this mess up baby’s schedule?

My LO has been sleeping through the night (most nights) for a few weeks now. We usually do a bath at 6:30/7pm- pj’s and lotion then nurse her and she’s usually asleep by 8pm. Tonight my fiancé’s cousin is visiting from LA and we would really like to get dinner at his family’s restaurant at 7pm when everyone else will be there.. is this a bad idea or will one night not hurt?
