Every time I go to Serendipity, it's always extremely packed, so I always opt for the to-go option. Their food is mediocre and I wouldn't recommend this place as your first choice for lunch.   Their frozen hot chocolate is pretty decent, but it definitely does not compare the New York store.  If you never had the frozen hot chocolate, definitely go try it out!  But don't stay for anything else.  The decor is very trendy and cute, but beware of the overpriced menu!
