casually fancy dinner date place in Houston?

LF a place that is fancier than casual but just a skosh less fancy than "upscale" or "trendy"

I want to take my date to a nice place without making it look like I'm trying too hard

quiet, borderline romantic

can accommodate walk ins (the exact time is in flux so can't easily make reservations)

within 20 min fri night drive of Montrose

maybe italian, sushi, french, ramen, mexican open to anything really
