While I have thougght about it, but don't have the capital... and I don't assume you to, either.... you've got a strong enough the fan base to start a campaign for recipes... obviously you'd get flooded with nonsense "what's the last thing I made at 4:30AM while gaming and I can't pay attention to it" stuff... but if there were a way to weed out the nonsense, you could legitimately try enough things out on a weekly basis that you had a solid ground for a theoretical restaurant...
So let's say you have a best recipe contest... tournament even... people have to buy food anyways... so eat our food that sounds decent and check it out... I've got 5-10 recipes I'd put up against any chef on food network (and I mean that)... I don't know how many other people are talented in culinary arts... but you can tell a bullshit recipe about 5 ingredients in...
Maybe a contest? Maybe a video on the best you encountered over a month or two?
