5th Ave is a favorite
Del Mar, Osteria Tulia and Del Mar (top level preferably) are a few of our favorites
There's also a really good French spot there (which has American fare as well) - can't remember the name but it has the French flags outside
The beach is right there too, as are million-dollar houses on steroids. Take a drive around to see the views, and if you're so inclined, park the car and hop in the Gulf. We love Loudermill for the beach scene, but all of them are good
Sox - do the tour of Fenway South before the game. Well worth it, they let you on the field and often times you'll see guys meandering around. Got to talk to Dave Roberts and Jim Rice when we did it
We like the seats down the left field line, under the overhand. A favorite spot is halfway between 3rd base and the foul pole. Great little sausage stand that also serves beer, and the bathroom are right there as well (Pops is 73, so he's always on the lookout for them)
In between the tour and game, a lot of people (including us) were tailgating. Get a 12 pack and some sandwiches and enjoy the scene
Twins - Similar to the Sox, they have a bar down the left field line. This one though is massive, with seating all around it and a bunch of tvs. We got seats behind home plate the day of the game via stubhub and had a blast
I prefer Fenway South, but both stadiums are great
