I don't know where you are but we have for years had pizza and pasta places that you could order and take out or grab a table and eat. The pasta is generally spaghetti, lasagna, baked ziti, ravioli, that sort of thing. They also serve sandwiches, like meatball sandwiches, veal parm sandwiches, that kind of dish and calzones. The food is basically pretty good.
Have never seen a fast food pasta place sans pizza and calzones however.
It might work.
Could be a lunch type place, lunch size pasta plates, salad, sandwiches or you could be going for the lunch and dinner take out crowd.
Make sure you have a good business plan and have thought it out well.
I wish you luck.
We almost never go to them. We like to sit down, have a drink, and let someone serve us. We go out for a bit of relaxation.
