Wooo Hoooo how awesome!!!

I really hope it works out for you all, I guess the only tips I have...

Research your market, or the one you want to tap into. That will really determine the type of restaraunt, i.e. level of service etc.
Make yourself different, not just another....
Keep a menu small, and simple, too many flavours, taste etc can be so overwhealming
Local, produce is a massive winner, support the locals, seasons etc
Any wineries in the area, maybe you will be able to give them a plug but using their wine as a special deal for a month
Get to know all the suppliers, build relationships
Tapas and small menu food are a great way to capture people dropping through looking for a snack, also converting to entree options or a Tapas Meal
If you are hiring anyone to help, really test out there knowledge, and skills.
Smart Advertising, get online ASAP, it can be a simple web page with a menu, you can even just set it up as a blog, no fee's etc. Facebook, Local Newspaper, when you get close to opening, maybe try and get something in the local paper.
Does it need a facelift? Keep it simple and small $$ so you aren't expending heaps before you get going.
Can you speak with the previous owners of the property - what was there?

I really hope it works out and that in 12 months time you will be going strong and reaping the rewards it will be a lot of hardwork but I bet it is worth every minute!!
Have fun!!!
