If you want a dressier more formal restaurant, I would suggest Goodhues. Their menu is around $20-50 per person.
If you want something more low-key but intimate, Cafe Malaga is really nice. Smaller seating capacity, smaller portions but made to share. Very affordable! Around $10-$20 per person.
When the weather gets warmer, I would suggest Poppy's. There is outside seating and they have live entertainment. The green bean tempura is mighty good as an appetizer. Around $10-$30 per person.
