Unbelievably, my son has a hockey game at the same time as the Harvard game this weekend so I'm going to miss this game for the first time in a while.
I'm not sure what "bubble" tea is but I wonder if the "bubble" is an infuser? For those of you looking for food in Harvard Square, let me suggest John Harvards:
https://www.johnharvards.com/ If anyone with a car gets in early enough, I can recommend a few other spots that are in the area. Among my favorites are: Redbones in Davis Square, The Miracle of Science in Central Square, The Cambridge Brewery in Kendall Square and The Sunset Grill & Tap in Allston (which is actually the part of Boston that Harvard's rink is in). The first 3 are all in easy walking distance from T stations on the red line (which runs west to east in the following order: Davis Square - Porter Square - Harvard Square - Central Square - Kendall Square). The Sunset Grill is about a 5 minute drive from the arena (but about an hour by the T).
All 5 places are great watering holes with great food.
