"We get very good reviews and check for customer feedback really often and we score high all across the board"

Who is your target audience?
Who are your main buyers?
Have you asked your customers what holds them back from coming to your store (more often)?
Where are you located is it easily reachable?
Can you do some events like (vegan) film screenings, vegan dating night (in cooperation with a dating platform) or is there no space?
