What you didn't explain was your model for making revenue.

Who is your customer?

Is it the end users...or paid advertisers? The restaurants? A third party?

I wonder if you've thought this through.

Loads of people have this SaaS idea...they dump resources into creating it. But why didn't they line paying customers up FIRST?? I don't get the mentality. It's backwards. You prove the thing is viable first; then you develop it. Why people persist in doing the opposite baffles me.
