I LOVE tuna melts. I have had a million of them. But, I have never had a tuna melt as good as the one from Crystals' restraunt in Rehoboth Beach, Delaware. I worked there probably about three years ago and have always eat these tuna melts but never knew what I was missing out on. Everywhere else I ate they always did the traditonal grilled rye braed, mayo, tuna, and provolone cheese. But Crystals has two different kind of chesses and they put tomotoe in the sandwhich. I know not the best food in the world, but sure is my favorite.
