One recommendation is that you could also include a community vote, so that people that are using this application can also give their impressions on the different restaurants and vote up or down different places.
I have a couple of technical questions as well, to which hopefully you will give me an answer: What is the architecture of your application? What architecture do you use for the client-server communication in the application? Do you use any cloud services? What is your method of transferring information from client to server (JSON, SOAP)?
Thanks and good luck with it!
The app looks like it would be useful, though it all depends on how many businesses you get to partner with. (Since it's only for San Diego, I haven't actually downloaded it. If it comes to my city I'll give it a try.)
I assume you have lots of competition in this space (location-based deals and events). Do you know who the big players are and what your "niche" or main advantage over them is?
