Under $50/person without wine: Matt's in the Market (near Pike Place) if you want a romantic dinner. Ototo (near top of Queen Anne) if you want the best sushi and sashimi in Seattle. Cafe Lago (near Montlake) if you like great pasta and dessert.
Recently another visitor was looking for Monday night dining options. I've attached the link to her query (I think some restaurants were closed Mondays but she eventually found something that worked).
Why don't you take the time to scroll through the site instead of asking the same question already asked several times. If you have specific questions, we're here for you...
