Lexington bar to watch game and eat well
A little late, but The Copperhouse Tavern just off the winter st exit in Waltham is a great place to catch the game in the area. Lots of tv's and a great beer selection - although some are priced too high. Sandwiches, entrees, and appetizers have been good so far - not a fan of the burgers (bland) or the pizza (crust was lacking flavor and the sauce is too sweet) though.
I went to Vine Brook tavern and had a great meal. They had one tv on the football game and changed the other one so I could watch baseball. Terrific Caesar salad with a challah crouton and chicken al mat tone Great place. Only weirdness was they had great pizzas that are only "Togo".
I don't know Lexington as well as I once did, so am not sure where the TVs are. You could call Yangtze River and ask.
Otherwise, there's an Irish pub (small national chain) called Waxy O'Connor's that will certainly have a crowd of sports fans. http://www.yelp.com/biz/waxy-o-connor...
The Vine Brook Tavern has TV's over their bar, and decent food, I'd say. If you like Margarita's, there's one near you just over the border into Bedford. As long as you're going that way, though, go a little further and have decent bbq and watch the game at the FireBox in Bedford, probably about 10 minutes from the aloft.
