It's been way too long since I have been out to dinner in Boston and this Friday I am headed in to see the Stones at the TD Garden. I know the North End and Back Bay are within walking distance, but I can't seem to think of a place I would like to try or revisit in that area. My dining companion is gluten free and we would like to find an inexpensive (under $25 per main dish) place but still have an enjoyable meal since it isn't too often I am venturing out these days. Not looking for anything too adventurous, just a decent Italian, American, Steakhouse, no Asian (again dining companion is gluten free- no soy for her). We will be dressed fairly casually for the concert as well. For all I know, there could be some worthy eats just across the street from the Garden, but I have been so out of the Boston dining scene loop I don't even know they exist! Extra points for a nice outdoor dining option, it appears the weather will be just fine for that. Many thanks for your suggestions!
