Removing bullets in sidebar

Hi,

I have 4 textwidgets below my blog’s posts.
I can’t get rid of these bullets.

My blog:

http://www.letthemstare.com

I’ve tried:

1. .entry ul li:before, #sidebar ul ul li:before {
content: “0BB 020”;
}

2. list-style: none;
list-style-type: none;

3. #sidebar ul {
list-style-type:none;
}

I’ve tried more than that but that’s what I remember.
Anyway, none of which was successful.
My theme is maninfest and it doesn’t support sidebar.
