How Profitable Is Eatery Business?

I am thinking of starting an eatery on a low budget in my area in abuja. There is nothing like that in the area. The area is busy and has lots of traffic. The place will be a cool place where people can come in and take snacks and drinks. i am thinking of renting and joining 2 shops to achieve this with transparent glass and tv. 
I look forward to hearing from you guys. Is it profitable and what are the challenges?
