Some of the employees (main chef and some of the order takers) are rude. Forget about substitutions if you have allergies. The chef does not care. Definitely not the place for people with ANY food considerations.
Their emails say "Intermezzo is open all year long" but note that they are sometimes closed without warning. Make sure you get their emails and only go on days you get the email or call there first. Walking all the way there and finding them closed is annoying, especially on short lunch days.
Check your order if you get it to go (this is good for any place you go but especially here). Mistakes happen often.
Their tomato soup is like tasteless tomato water (the grilled cheese that goes with it is almost equally tasteless).
