So here's an odd one for you. Once a week, I organize dinner for a large group of friends scattered about the East Bay. On average, about nine of us turn up, though in theory we can hit as high as 15. We're moderately flexible on location, but are pretty well tied to 680; anything from Pleasant Hill to Pleasanton or so is fair game, though we'll stretch a bit on special occasions.
The kicker: one of our regulars has several crippling food allergies, along with Adult Selective Eating Disorder: for all practical purposes, if there are not french fries on the menu, he'll be nursing a drink all night.
Since we've been doing this for quite nearly a year now, you can imagine that the fries-friendly options we know about are getting pretty stale, especially around the Danville / San Ramon area. Breaking up the samey Diner type fare without leaving said friend out in the cold would be wonderful, but we're coming up short on ideas. Does anyone have some appropriate recommendations, particularly for a group of this size?
