I am not a vegetarian nor a vegan, but I would still choose Soi Soi as my favorite burger joint in Helsinki. Soi Soi is definitely not a place where you can go to poke a piece of salad around your plate. It’s one of those places where you probably need to discreetly open up the top button of your jeans.
This small and cozy vegetarian place offers different reasonably priced burgers, pitas and plates with seitan, soy, tofu or hemp for protein. I recommend taking the Finnish way and choosing rye bread instead of white for your burger. Also the sweet potato fries are something not to miss!
When it gets really busy in Soi Soi though, it often ends up in a bit of a chaos service vise. You will get your order eventually, so just sit down, sip your organic lemonade and relax! If the place looks completely full, just keep on walking; Vaasankatu street hosts many street gastros – vegetarian as well.
