When visiting South Lake Tahoe definately take time out to enjoy a cone at Rachardson's Ice Cream Parlor. The line might possibly be out the door but the staff is very organized and it moves quickly. There are not 31 flavors by any means but what they have is delicous and the scoops are HUGE.
There are a few tables indoors and several outside. We loved sitting outside on the picnic tables underneath the georgous pine trees.
My dad was traveling with us and is a huge ice cream fan. He was very pleased so we went several times. I highly recommend.
P.S. I only rated 4 stars because of the long line . That can't be helped though because the place is great.
