I really liked this place. Got a strawberry shake, and it reminded me of Red Robin's shakes which I love. Also, the burgers were delicious and surprisingly not too oily compared to other gourmet burgers. The one thing you have to try is the onion rings. I hate when onions are too large in onion rings, but Holsteins does it right with the thin onion strips and delicious breading.
My only complaint is the wait time. The first time we went, they told us it was a 30-40 minute wait for our food no matter what we ordered. Food NEVER takes that long to come out even in a steakhouse. We got lucky the second time we went because the waiter told us it was a 30-40 minute wait, noticed we were in a rush, and ended up pulling strings and got our food out in 10 minutes, so kudos to service!
