Final Research Question Proposal

I have decided to stick with the same question i presented in my "Tentative Research Topic Proposal": What aspects of fast-casual restaurants make them more appealing to customers when compared to fast food and casual dining restaurants? Because this week is our break, i will be able to put more time into studying fast-casual restaurants and i will hopefully be able to make a CRJ for 2 different fast-casual restaurants. I understand that i must focus more on the fast casual restaurants and less on the pros and cons of the fast food and casual dining restaurants. I will still take that into consideration though when comparing them to fast-casual restaurants.
