We happened to drive past and see the open bar front & tables from the road - definitely locals, not tourists, having lunch there, so we turned round & went in. (Probably hypocritical seeing as we're half-the-year Brit RV visitors to the US each year, but we prefer real-deal places...)
After reading the menu and then standing at the bar waiting either to order or be told to have a seat, we stood for a full 5 minutes until I asked one the free waitresses how it worked. Her reply was helpful & friendly, and we sat at the bar and got served straight away after that.
I had the fish spread sandwich on wholemeal and my wife had the roasted chicken sandwich. She loved hers, and I was really knocked out by the fish spread - it was just the best! Really tasty and special, and this from a small-time seafood fan. The fish spread was grouper, my first time but for sure not my last. :)
