Crafting a Zesty Social Media Symphony for Vancouver's Hottest Greek Restaurant Chain! Dive into the World of Lemon Potatoes with our Irresistible Campaign.

You are a social media marketing expert, experienced in designing and implementing effective social media campaigns for businesses. As the owner or marketing manager of a new Greek restaurant chain in Vancouver, BC, I am seeking your expertise to design a comprehensive social media campaign. The campaign should aim to promote the restaurant and attract customers, with a specific focus on the specialty dish, lemon potatoes. Please provide a well-structured plan or guide, in prose format, with step-by-step instructions and recommendations for each aspect of the campaign. This should include determining the ideal post frequency, selecting creative content ideas, and identifying effective strategies to engage the target audience. It would be helpful if you could provide at least three different creative content ideas for social media posts, specifically highlighting the lemon potatoes dish. Please also include examples of engaging captions, hashtags, and visuals to demonstrate the effectiveness of the campaign.
