Logo Sizing on Side Bar of Cafe/Restaurant Theme

Hi, I’ve been talking with user Noda regarding this issue and since I never heard back today, I just wanted to make sure it’s being looked into (this is one of two things I’m waiting on to launch my site). The last reply I received said to use “bigger value” and I tried using bigger logo files– is that what you mean? I can’t seem to increase the size of the logo. Please refer to my other post on this for log-in info for my site as well as logo files if needed. Thank you for your help with this!
