My mom and I have tix for Spamalot at the Ordway on Saturday night, and we'd like to eat someplace before. It's not necessary that it's walking distance, though that would be nice. I don't want anywhere terribly pretentious or uptight, but would like it to feel like a treat, so nothing too casual either, since we'll be dressed up. My mom's not good with exotic, so sushi is out. What would you recommend?
