I'll start by saying the vegan oreo milkshake was one of the best milkshakes I've had in my life (vegan and nonvegan included). I HIGHLY recommend trying it. However, the Philly was lacking. I got the Supreme with fries for like $18 and feel like I was overcharged. I'm pretty sure it is just beyond burgers chopped up with a ton of mushrooms and then drowned in way too much dry seasonings that don't go together and then very little of the vegan cheese. The fries were stale tasting and also just covered in dry seasoning. The gluten-free option is just paying a $1 more for some reason to have it all placed on a big slice of iceberg lettuce.
In conclusion: go for the milkshakes but skip the food.
