I managed to make it in before closing, and I'm glad I did. I had an amazing southwest burger and some sweet potato fries. The burger was a little more done than I ordered, but was fantastic, anyway; a very nice blend of spice and flavor. I'm a big fan of sweet potato fries, and theirs are among the best I've had. Crunchy but just mushy enough inside, they left me sad that I didn't order a double portion.
I'd like to give The Grill on Main five stars, but their operating hours are still lousy. That said, I got prompt, friendly (take-out) service, despite walking in 15 minutes before close.
