If you are looking for a good vegan veggie burger check out Johnny Rockets. It's one of my favorite restaurants to go to for a good vegan veggie burger and fries. The burger and bun are both vegan and at least at the one I go to I see them cook it on a separate grill.
The veggie burger at Johnny Rockets is called the Streamliner. It is a vegan Boca patty topped with grilled onions, lettuce, tomato, pickles, and mustard. I add ketchup once it is brought to the table.
I like Johnny Rockets. I love that they offer a good veggie burger and fries and I like the atmosphere. It's fun! I like when they play some good diso music and dance. It's a family fun restaurant.
