In the Gulf of Mexico, they sting; on a plate at Tay Do, you get revenge. It is a sugary sweet revenge, tempered with the warmth of roasted garlic and the bite of fresh red onion. If you've never tried chilled jellyfish salad -- or Summer Delight, as they call it here -- you will be surprised at the tastiness of Tay Do's. If you have, well, ditto. The translucent jellyfish strands look like thick rice noodles and offer up a slight, pleasant crunch. Their flavor is mild, more of a conduit for spicy-sweet fish sauce. The strands are tossed in a salad of sliced shrimp, pork, cucumber and shredded carrot. Try it atop one of the shrimp chips served on the side. On a hot summer night, it goes perfectly with a chilled glass of beer.
