I finally made it to Nielsen's last week. As it was lunch time I opted for one of their famous "grinders."
Can't say I was overwhelmed. The sandwich was clearly made with care, but it was chintzy in terms of meat.
However, the fries were REALLY good. Hot and crisp. No need for the "fry sauce" that accompanies them.
I will go back to try the custard next time I'm in the vicinity.
