Friday night: avoid -- or head straight for -- Harvard Square!
Just alerting everybody: tomorrow at 5 p.m., Harvard Square turns into Hogwarts Square. Potter-mania is taking over, with concerts featuring Harry and the Potters, Draco and the Malfoys, and the Hungarian Horntails in Hogwarts Yard.
I mention this here because not only will restaurants likely be packed, many of them staying open late and several are having Potter specials. Upstairs on the Square will have a special family menu (featuring butterbeer and polyjuice potion), Grendels will be serving beer from Middle Ages Brewing, and supposedly, Toscis will be "back in Harvard Square for this special evening!"
Sounds like fun. But you might want to stay away if you're looking for a quiet adult evening.
