Sorry, but I also have to agree that Double Jacks is not worth the trip. My wife and I were excited when it first opened, but will likely never return after trying to give it the benefit of the doubt three different times.
1st trip: Bison burger was clearly pre-frozen, as the meat was so compressed that it had no texture whatesoever. As a result, it was also horribly dry once cooked. For $12, my wife was not happy at all.
2nd trip: Food was OK (we avoided any wild game this time, assuming it all arrived in pre-frozen form), but the service was HORRIBLE. We sat at the bar, ordered a beer and put in the food order. 40 minutes later, with no sign of food coming, the bartender informed us that our order had been lost, and he had just re-entered it. It took another 30 minutes after that for a chicken burger and a grilled cheese. No apologies, and most definitely no free beer on the house or any sort of other goodwill gesture--not good for a brand new restaurant. Thie was all compounded by the fact that one of the owners was right behind us telling a customer about all of his plans to franchise this place--learn to walk before you can run, buddy.
3rd trip: Got a "stuffed" poblano burger. If I hadn't known it was "stuffed", I NEVER would have guessed it--I think there about 2 little specks of pepper inside the meat. Again, for around $12. So, yeah, 3rd strike, you're out.
The one positive--the fries are really good. Which is a shame, because nothing else seems to be up to par. We were really hoping they would work out the kinks, but after about a month, nothing seems to have improved.
Good burger recommendations: Emmett's Tavern in West Dundee. They have a really nice (freshly pattied) bison burger for around $10. Country House in Geneva also makes some good burgers--beef, bison, ostrich. Finally, one other new joint in Geneva just opened called Urban Grill. Basically a pick your toppings type of place, but with beef, turkey, veggie, salmon (ground), etc., as the meat choices. Good fried pickles, too.
Oh, and Brass Brewery in South Barrington has some pretty tasty mini sliders for $1 on weeknights (from 4 to 7, I think?). Much bigger than what you would normally associate with a "slider".
