If you’re in search of a peaceful meal full of vegetarian Japanese food, head to Cha-Ya in the Mission. This small spot offers dine-in on a first-come, first-served basis, and like a fine-tuned machine, there are almost always tables available immediately or after a short wait. Once seated, try the massive vegetable-topped soba salad, the thick curry udon, or one of the many sushi options, like the signature Cha-Ya roll with avocado, yam, asparagus, and carrot. The best part is that no matter how buzzing this place gets, it's always a few decibel levels lower than outside, so you can continue to relax after a day of baking in the sun at Dolores Park.
