I was on my phone earlier and didn't have all my bookmarked information about the vegan options in front me but about Red Robin, the Onion Bun, Whole Grain Bun, and Yellow Seeded Bun is vegan. The endless steak fries are also vegan and the Red Robin Signature Seasoning is in a big container on the table so you can see all the ingredients and it's also vegan (and delicious! I wish they sold their seasoning). Also, I think the sauce is actually vegan, because it says it's a Dijon mustard which I've never checked but I'm pretty sure is vegan. I just doublechecked and the Red Robin menu says the name of the burger is "BOCA Original Vegan Burger" so it is the vegan version, but the Gardenburger looks like it has eggs so just be sure to ask for the Boca instead of just ordering a veggieburger. (I'm glad Red Robin is vegan friendly, I just wish they also had a Boca chik'n patty to substitute for their chicken sandwiches in addition to the burger substitution
). I've never heard of any other restaurants (besides a few in Disneyland) that have vegan Boca patties though, all the other ones seem to be Gardenburger, which isn't vegan, or the vegan Amy's burger.
Also, does anyone know why Red Robin has the big Boca patties resembling the gourmet Red Robin burgers but the Boca ones sold in stores are the size of like a mcdonalds burger? I really wish I could find some of the bigger patties in stores, I got full half way through my Red Robin one and then had leftovers.
Sorry for going off topic but I keep wondering if Red Robin just special ordered them or if my store only carries some sort of smaller version of Boca's.
