I have only been to Melt once, but it was awesome and I do plan on going again. I can honesty say the grilled cheese I had was the best I've ever had. The beer selection is very good and you can find some great drafts you don't see many places.
My only contention with the place is the wait. I can understand having to wait for a table, but it took about 40 minutes to get our food after ordering. Let's remember this is grilled cheese not Peking duck
