Current Kosher options in Boston.
The family will have to be in a Boston hotel over Shabbos. Does anyone deliver to hotels or will this be one of those out of the cooler trips? Also, any decent restaurants for Sunday or snacks for motzei Shabbos? In advance, thank you.
I've not been to Boston in a really long time, but check to see what the Butcherie might be able to do. According to their web site (www.butcherie.com, phone number is 617-731-9888) they have a variety of prepared foods. Maybe they do Shabbos specials, too - a lot of places like that tend to have some sort of special (soup, roast chicken, and kugel, usually), but I don't know if they would deliver.
If you are looking for shabbos - if you can make it to Brookline - The Butcherie on Harvard Street has a full takeout counter. Not all their meat is GLATT (they sell both) - so depending on your kashrut needs, be sure to ask.
Other options for shabbos food that will deliver:
Rubin's Deli in brookline will deliver shabbos meals
Milk Street Cafe located downtown may provide shabbos food delivery through their corporate catering division. Their restaurant does not offer shabbos food to be purchased.
In terms of Saturday night and Sunday - all your kosher options are going to be in Brookline. Given that shabbos is over late, not sure what will be open - likely only Taam China.
Good options for Sunday include:
Cafe Eilat (pizza/dairy)
Taam China (chinese)
Rami's (middle eastern)
Jerusalem Grill (Israeli)
