Thanks for checking in with me. Yes, I received your email, but since we don't have an opening date yet, we haven't made plans in regards to food truck vendors. Once we have a more definitive opening day, I would be happy to discuss having you guys and your food truck at the distillery.

Thank you for the update. I completely understand the situation and will patiently await further information on the opening date. I look forward to the opportunity to discuss the possibility of having our food truck at your distillery once everything is confirmed. Please feel free to reach out to me anytime. Thank you again for considering us.
