Red Robin has a couple of options for vegetarians. We usually eat at the Red Robin in Westminster and here’s the menu. Veggie hubby usually gets the GardenBurger without the bun, wrapped in lettuce. The GardenBurger is advertised as Vegan. Red Robin also has a boca burger. You can also choose sweet potato fries or a salad instead of their bottomless fries.
If you prefer a bun to lettuce wrapped you can also request a gluten-free bun for a small up charge.
I usually get a double tavern burger with a gluten free bun and sweet potato fries. Pictured here however is a Bacon Burger with a regular bun and bottomless fries because it was my birthday and I splurged.
