Here are some tips for enjoying sushi at the restaurants near 320 11th Ave, San Diego, California:

1. **Explore Varieties**: Try different types of sushi, such as nigiri, sashimi, and rolls. Each offers a unique flavor and texture.

2. **Ask for Recommendations**: Don’t hesitate to ask the staff for their specialties or chef’s recommendations; they can guide you to popular or unique options.

3. **Savor with Soy Sauce**: Use soy sauce sparingly; it's meant to enhance, not overpower. Dip fish-side down to retain flavors.

6. **Pair Wisely**: Consider pairing your sushi with sake or Japanese beer for a complementary experience.

7. **Buffet Caution**: At buffets, pace yourself—start with smaller portions to try a variety without overindulging.
