Weifung, im not sure if Jimmy is a wedding cordinator, what i knew was he helps with the paperwork and scheduling appts for my cordinator. Just correspond with LK via email. My impression is she is efficient and professional. Did answer my several enquiries promptly, so kinda assured.
Haahahaa, hope to help but me no expert in wine. Why don't you go to one of the 2 winery shops proposed in the contract and seek their help? What i know is good wine definitely cost more.
