I've been to Rhino a few times now. I dont live within walking distance so I usually go with a friend that lives nearby or when I'm just near there for another reason.
I do always grab a sandwich. They have a list of vegetarian and a list for meat sandwiches. On the latest visit, I got the club. It's nice. Not a double decker of anything so it's just enough food. Could have used another strip of bacon though. One half didn't seem to have any.
They have a fridge there with sides like slaw and broccoli salad. They have soup. They also offer quite an array of special sodas in cans and bottles as well as lotsa beer and even wine. Some cold, some not.
While waiting for my to-go order, I browsed. I dig that they offer bitters, syrups and vermouth. I was pleasantly surprised to see a bottle of real orgeat (French) so snatched that up for my at home bar.
Also, great patio in the side. Just watch out for the parking lot as some patrons seem to make their own spots making it a bit hard to navigate.
