Short cab ride to Rue Saint Jacque, Jackson and Taylor. Great little neighborhood French restaurant. You could easily walk back to your hotel (downhill, take the cab going, all uphill). Even with wine you'll easily be under $150.
Another neighborhood place that's outstanding is Luella, Hyde and Green. Again, a cab ride but not long or expensive. When done, hope of the cable car back to Bush St., if runs right in front of the restaurant. Agan, outstanding food, good wine list, super service, very non-tourstiy.
