Some foodie tips, all my opinion of course:
Best Ramen - Sawaii Ramen, 2240 Irving SF. Around $10-13 for a bowl/person. Seriously this shit is the bomb. Best ramen i have ever had, hands down. Get the tonkatsu ramen with extra porkbelly and egg. You will thank me. Also, go lunch time, food seems to taste better haha.
Best Beef - House of Prime Rib, 1906 Van Ness SF. Be ready to spend $40-65 a person, upper limit with inclusion of alchohol. I've had pretty freaking good steak and prime rib at lots of restaurants and this place right here is my favorite. Its really my favorite restaurant now that i think about it. Very simple menu(only prime rib and "catch of the day" which tends to be salmon) with good sides. If you go here get the creamed spinach. Moderate wine selection. Good for those on keto/primal diet, just order two servings of the spinach.
Best Sushi - Sushiholic, 112 Vintage Way Novato. $15-40 a person. Really fresh fish combined with awesome awesome rolls at a good price. The piece of fish they give you, be it sashimi or sushi is just massive. I recommend the hawaiin butterfish, toro, and salmon belly.
