I agree with Patty! High Tea is a really fun experience and a great, quiet way to relax in the afternoon.
The food (as usual) is great too.
I think all of the empty tables can be a bit misleading. I don't think that they book the entire Palo restaurant for High Tea but instead only use a small portion of the total number of tables.
When we went it seemed like they were using maybe 10 tables max. Although I think only 5 or so were being used at the time.
