Four words: short rib grilled cheese.
It was magical.
Four out of 8 people at my table ordered it and the other 4 wished they'd followed suit.
The Grand Lux is a good choice when you're trying to eat a good meal at a good price, but don't want to be all cheap and McD's about it. The prices are fair for the portions and quality of the food.
The service was off in one instance where everyone got their food except me because of a kitchen error (I think my plate was sent to a different table). However, I'm not bitter because the server was straight up about it and very apologetic. He vowed to get me my grilled cheese right away and even offered a side to hold me over. When I said I didn't need a side, he insisted, so I went with french fries and he brought me the a huge bowl of fries. I'm talking 2 or 3 times a normal meal portion. Not necessary, but I appreciated the gesture.
Oh, and I definitely appreciated that grilled cheese!
