It's very rare that a place gets full 5 stars because of how honest i am. But this place was amazing. The food, the staff, the super chill atmosphere i couldn't ask for anything more!!. I wish we took pictures before scarfing everything down, but it was so good!!. I personally can't wait to come back again. 😇😇🥰🥰

The spicy jam burger is my jam! ?? chef's kiss cuz gosh dang it was delicious. It has a crispy crunchy slice of cheese in it. Went for the first time with friends. The blue cheese burger was pretty tasty as well and I don't even like blue cheese like that. The monkey fries were good but not something I would order again. Almost thier spin on animal fries. I'll just order the jam burger twice instead. I got the lavender lemonade as well, had me feeling lovely, even...

The customer service is fantastic! The burger was absolutely AMAZING! One of the BEST I have ever had! I’m going to have to come back and get one for the road tomorrow! I tried the burger with the Spicy Jam. It’s a MUST!!!
