As above, very True, be careful with the word consultant!!! Generally if its financial advice or business management advice, your accountant may be able to help more (and seeing as they will want you to succeed so they get paid for their work) , as they will have learned a lot from running their own practise if self employed in terms of HR, marketing etc.
If shes just involved in Chefing, Menu etc then it may be a good thing, the main idea is to make sure your getting the people in the door!!
I know i picked up more from first 2 years in business than i got from appointments with Marketing/HR/Etc consultants.....
