I'm no vegan, but Planta Burger has turned into a regular for me.
The menu is pretty simple - four kinds of burgers, a number of sides, and drinks. All of it vegan (or 'plant-based' as they call it).
The burgers are quite good - a bit messy to eat because they're bean based and the patties tend to fall apart, but tasty and enjoyable.
The best one is the classic burger. The california burger is a real mess, and winds up just being kind of bland. Jackfruit burger and "crab cake" burger are both good.
As for sides - I've had three. Regular fries are way too salty (or at least they were the last time I had them). Onion rings are fine. But what is really good is the fried cauliflower. Spicy, and really enjoyable. There's an upcharge to get anything other than fries with your burger, but it is definitely worth it to get the cauliflower.
Service is friendly and relatively quick. Seating can be a bit tight, but it seems like a lot of their business is takeout.
