I am going to get dinner in Porter Square at Christopher's, which appears to have lots of tasty veggie-type foods as well as meat. Mmm. I never know where to go when Mary's is closed.
If anyone else wants to show up too I will be super happy. =) If you let me know you want to come, I can even make sure there will be a seat for you.
There are directions and a menu here:
