the total boston experience tour was very interesting and highly recommended. the paul revere part was very informative. for those who'd like to linger more inside harvard and MIT, this is not the tour to take. i would have rated this tour a 5 star if not for the hard push and hard sell to eat at "no name restaurant" from the tour guide. place is aweful with mediocre food and drinks. "legal restaurant" is still the better choice which has two locations. the best one is by the south end of the pier next to where the "no name restaurant" is. PLEASE, STOP PROMOTING THAT PLACE. it's not good at all.
