Is the outdoor seating area dog friendly?

It's not.

It is not, but to know for sure ask them yourself. Call and see, never hurts to ask.

I'm sure it's ok if it's a service dog, but there are small rocks outside

I don't think so. I've never seen dogs there.

I believe the back patio has a ramp available without going through the restaurant. However, I'm not sure if dogs are allowed or not.

I don't believe it is dog friendly. I have never seen one outside and I eat their frequently.

No. The area is closed off, to my recollection, so you would need to go through the restaurant first.

I don't think it is.
