Logo Sizing on Side Bar of Cafe/Restaurant Theme

Hi,

I have a new website at prosperdetox.com and I’m using your Cafe/Restaurant Demo (purchased the High End theme through Mojo Marketplace). The problem I am having is with the size of the logo on the left side bar (please visit the homepage of my site to see or check out the screenshot I attached). It is appearing much smaller than what I would like and the only info I find in the theme documentation says:

Step 1 – Login to your WordPress Dashboard.
Step 2 – Go to Appearance > Highend Options > Logo Settings.
Step 3 – Upload your logo in any size – It will be resized to fit the header bar.
Step 4 – Upload your retina logo – exactly double the size of the regular logo.

However, no matter what size I upload for the logo it automatically gets resized. Can you please help me with this? Thank you!
