Can you help me think of birthday ideas for my mom on Saturday?

I live in the west palm beach area. Usually I take her to the movies but I want to do something more.

In the AM i’m going to take her to IHOP and at night time i’ll take her to Ipic so we can have dinner and a movie. Any suggestions for things we can do in between that aren’t too pricey? I wanted to do the beach but the weather hasn’t been good.
