Where can you take girl on a date?

The mall or just Starbucks . Iv tried asking her ifshe wanted me tobuy her a coffee andshe said "aww thank you" and shesmiled but shecouldnt because she was going downtown. I wasgoing to ask her on a coffee date again orshould I try taking her somewhere else. She called me a hottie and a nice guy and when i kiss her on the cheek she smiles. We are really close and at times she feels awkward when I try anything intimate toward her but she says that I'm so sweet and kind. Where is a nice subtle place where she would agree to go with me?
