I have yet to eat a better vegetarian burger than at Pork Store Cafe. I don’t know what kind of drugs that put in the lentils, but their burger is absolutely delicious. I get mine California style, with sprouts and avocado. It comes with fries if you’re feeling frisky or a salad if you wanna watch your carbs. I love how cheesy and delicious it is, and how afterwards you don’t feel gross like you do after eating a quarter pounder. The service is prompt and the place is no frills and totally great for groups of friends. There are two locations in SF, and I’ve been to both, though I much prefer the location in the Mission, on 16th between Valencia and Guerrero. Remember to order a giant mimosa. They’re huge and cheap, double plus.
