Dear [Recipient's Name],
I hope this email finds you well. My name is [Your Name] and I am the
owner of Pops & Noni’s Cafe. I am reaching out to express my interest
in serving delicious food from my food truck at your upcoming event
[Event Name].
I recently heard about your event and I believe that the addition of
food from my food truck could be a great fit for your attendees. Our
menu consists of a variety of Barbecue and American food, which I
believe would be a hit with your guests.
I would love the opportunity to discuss further details such as menu
options, pricing, and logistics for catering at your event. I am
confident that my food truck can help enhance the overall experience
for attendees and contribute to the success of the event.
Please let me know if you would be interested in having us
participate in your event. I am more than happy to provide additional
information or answer any questions you may have.
Thank you for considering my proposal. I look forward to the
possibility of collaborating and serving food at your event.
Best regards,
