Most people's favorites are yummy yummy yummy, rockstar soap, and honey I washed the kids soap. I don't care much for food scents. So I've never tried these just because I wasn't attracted to the smell. Most LOVE these, so I wanted to mention them.
Overall, if you're new to LUSH, I'd say pick up a few bubble bars first, those are what impresses me the most, and you can get plenty of uses out of them. I'll never go back to Mr. Bubbles or any type of liquid bubble bath again. :)
