Sandwich business Questionaire

Hello to everyone
I have been intrested in starting my own business for about a six months now. Being an unqualified chef for 18 years, I thought i would set up a buffet and sandwich business.
So i went to college and have just finished my NVQ level 2 professional catering, ECDL level 2 (a computer course) to help me with my confidence and knowledge.
I brought a copy of Start Your Business Week By Week and started reading. I cant put it down now. What the purpose of this blog entry is to say hello to everyone and get a liitle feedback on some questions, for market research purposes..
I would be very grateful if you could spare a couple of minutes to reply.

Do you visit Sandwich shops?
Are you Vegetarian/Vegan/ gluten free?
What do you look for in a good sandwich/bagette/roll?
Do you eat Take-Away Salads?
What drink do you buy?
What is your favourite sandwich filing
Do you think ordering by Text and Email a good idea?

i am busy researching all my competitors in the area to get their prices.
I believe in customers getting value for money , which unfortunately most sandwich shops dont give you, I.E not enough filling, price too high, shoddy ingredients.

Thank you for taking the time to read this I hope everyone has success in whatever they are undertaking
