I've lived in Cleveland now for almost 6 years and it's taken me this long to visit Melt. Actually that's not entirely true. Twice now I've attempted to go but due to insanely long waits and random closures (Yes, I went to take a friend there it and was closed - for a vacation for the employees), I've yet to enjoy.
However a few weeks ago my roommate to me for my birthday. We went early, as to ensure we would not have to wait in the ridiculous line, and were seated right away.
Our server, whose name I wish I could remember, was incredibly friendly and knowledgeable. He made recommendations for me, the first timer, and made sure we had adequate time to decide between the delicious sandwiches. He was a really great server.
I went with the "Dude Abides" and my roommate the special of the month. Both sandwiches were enormous, with meat/cheese/sauce pouring out the sides. They were fantastic! Seriously, super delicious.
So if you haven't tried Melt yet, I suggest you do.
