I read your question before I could sign in on a computer so I hope you still need the help.
First, on a Friday night you will probably want to make a reservation. Some places I can think of that will meet your requirement for seafood dishes and pizza or lasagna type dishes are the following:
For Pizza and good seafood dishes and casual enough to go to a Bruin's game afterward, I would suggest Cafe Pompeii on Hanover St. They have a great red sauce , nice service and an atmosphere straight out of the Godfather ( and I mean that in a nice way!)
For Lasagna/pasta and good seafood dishes, I would try L'Osteria on Salem St. This is a very cute, moderately priced red sauce type of place that does really good seafood and pasta.
Lo Conte has amazing lasagna!
Also, for Bakery choices I would pick Modern over Mike's any day of the week and especially for canolli. If you are pressed for time, then Bova Bakery is at the top of Salem ( Salem & Prince) and on your way back to the garden.
Keep in mind that if you get bakery to go, The Garden does not allow bags. Hope this helps and I am sorry you felt you needed to take your original posting down. These are just off the top of my head so if you want more recommendations, let me know.Edited: 21 September 2011, 00:17
