Philosophical question - 1st time in Seattle (Nov 9-12). Should we try for fine dining while we're in town, or stick to chowders & oysters/fun not fancy places?

This isn't a budget question - we both love street food and we like tasting menus with wine pairings and are happy to eat anywhere and everywhere. Just trying to figure out if we should figure out a "fancy" place and try to get reservations. Would love your thoughts. Thanks!

(and yes, I've just noticed we're missing fall Restaurant week by a few days. Ah well. Happens to me for NYC and Vegas trips too....)
