Custom House offers a
3 course, pre-theatre menu for $46 if you go at 5.00pm or 5.30pm. I don't know how
special that is, though. On the
menu posted online, entrees go for around $30 and first courses for around $10. So maybe you save a few dollars on dessert?
I'm sure that other nearby restaurants have theater specials too, but I don't know the details.
