I like 'Tummy Tucker' Had the same idea for a sandwich business years ago. Thought of 'Sand Witches', but research favoured the former. I know it sounds a bit Australian, but everybody knows what 'tucker' is nowadays. You could have a cartoon character created (350 us dollars online service) and have him shouting, 'stop for Tummy Tucker!' As you grow, your name will probably get affectionately abbreviated to 'T.T's' . Hope this helps.
Sorry for the late response, you have probably already opened by now, but I saw a sadwich shop the other day and I thought of you! it was called "rolls dot scone"
