I just got my parents tickets to see a show at the walnut street theater and would like to also get them a gift certificate at a nearby (walking distance) restaurant beforehand. My parents do like to try the new trendy spots, really like unique atmosphere, but are not overly adventurous in what they will eat (no sushi, etc.). I want to get them a $50 gift certificate and am looking for a place that is not too expensive so that would cover their total bill. They do not drink, so I'm not worried about BYO vs. non BYO etc. Thanks!
