3.5. I've been here a handful of times, and have tried a handful of the items on their menu. I've never had anything bad, but nothing has blown my mind either.
Of course one has to get the frozen hot chocolate, which is yummy.
The place is decorated really cute and it's always crowded. Which I don't like because the wait time here always seems so much longer when compared to other places that get just as packed. And the hosts/servers are never really friendly. Maybe the place gets too crazy for them to slap a smile on.
I've never been to the Serendipity in NY, but I hear that this place just does not compare.
