Going to pimp out both my city and my national heritage a bit with some hot food takes...
BELGIUM
Enough talk about fries from In N Out, Shake Shack, or whatever other crappy American fast food place. If you haven't had
fries like this from a Belgian or Dutch Friktot, you haven't had real fries. The more mayo the better is my preference, but a good place will have dozens of different sauces to choose from, even ketchup for the unadventurous American tourist.
Belgian cuisine is very underrated overall and misrepresented a lot in America.
Moules Frites is one classic dish you can find in the states, but others such as
Waterzooi, or
Stoofvlees (or Carbonnade Flamande), or
Chicon au Gratin are also incredible. I've done a France/Belgium trip 3 times, and each time I can honestly say that the Belgian food impressed me more than the French food. It's the perfect comfort food, IMO.
Belgian waffles and Belgian chocolate are things you see a lot of in America, but none are anywhere near what you get in Belgium, although proper Belgian waffles are starting to become more common here. A Belgian waffle is not a bland, flimsy, batter based waffle from IHOB that you need to put syrup on. It's a dessert pastry, often coated in a crystallized sugar, and it does not need any toppings. You know the smell you get when you are near a good bakery? That's the smell that permeates the air of Belgian cities from all the corner waffle shops. They spread like Starbucks out there. For chocolate, you have to go for
pralines, which is something rarely found in America. It's on a whole other level than most of the stuff sold as "Belgian chocolate" out here.
SAN FRANCISCO
LA Taqueria has been voted the best burrito in America and it does not disappoint, but I think their tacos are just as good. Get the carnitas burrito "dorado" style.
The Herb Caen burger at Bill's is my favorite burger ever.
The Country Loaf from Tartine bakery is the best bread I've had outside of Europe.
Cioppino from Sotto Mare or Tadich Grill.
House of Prime Rib where I'm pretty sure they still have nothing but Prime Rib on their menu, as it should be. Vegetarians need not apply. I need to go there again.
Chicken Parm and spaghetti from Original Joe's for that feeling where you need a wheelbarrow just to be able to leave the restaurant.
