Blue Water Grill has the best fish sandwiches I've had here in San Diego. They have fish plates, sandwiches, cocktails, and chowders. Everything is fresh—they only serve what was caught that morning.
They don't skimp on the fish in your sandwich, so it's well worth the money. I always get the wild trout sandwich grilled in lemon-garlic butter with avocado added. Maybe one day I'll get something different, but the trout is just so good!
Tip: Even before this place was featured on the TV show, Diners, Drive in's and Dive's, it was very crowded at lunch time. If you want something here around that time, call in your order to bypass the long line, and pick your food up at the register.
