Late evening quick meal near Downtown Doubletree
We're taking Amtrak from Chicago to Boston in early April. Due to arrive in around 7, I'm assured 11pm wouldn't be a surprise. If they haven't fed us, we'll need a meal. We'll take a taxi to the Doubletree at 821 Washington Street, check our bags and then go out.
We'd like a place within walking distance, fast and inexpensive, doesn't have to be fancy, just fill our stomaches. Any suggestions?
