My first thought was that I'd agree with their "casual, coastal, comfort food" tagline - there's definitely the feeling you are at a seashore-style restaurant. They even have a small four-page newspaper on the table that talks about the restaurant, nautical myths and legends, special events and more. The Marblehead Grille is nothing like one of those chain seafood restaurants that are all over the place these days.
The specials were brought out on a chalkboard, which was kind of interesting. The menus weren't in any fancy binders but just on a regular piece of paper. The service was very good - they even accommodated my request as it wasn't on the regular menu. I had the tilapia, which was also very good.
Dessert options were presented in a different fashion too. A small treasure chest was brought to our table. Inside were pieces of salt water taffy, a folded up dessert menu and some small laminated cards that portrayed some of the desserts on them. Very interesting presentation.
They were busy for mid-week lunchtime, which is a good sign. I've been to plenty of Lehigh Valley restaurants lately that seemed like a ghost town. So kudos to the owners and staff.
I'm looking forward to heading back to Marblehead Grille and Chowder House once I can eat shellfish again. The clambake on the menu sounded awesome!
