We have been to many HRC's throughout our travels.
When we arrived at the Baltimore Marriott Waterfront Hotel, we dropped off our luggage and went out to explore and get a bite to eat while waiting to check-in. We began walking and saw the trademark guitar, clinging to a towering smoke stack. We quickly decided on visiting a familiar chain, being tired out from traveling.
There was a short wait for our table. We took a restroom break, which were downstairs - a bit inconvenient, but it is a really old building. I probably would have asked if there was a handicapped restroom, do to a disability, but I generally don't like to make a fuss. My advice if you have mobility issues, ask if there is another restroom.
We ordered our "usual's", nachos, burgers and salads. Service was cheerful and prompt. Food was exactly what we expected (yummy). As with all HRCs, atmosphere is awesome.
If you are looking for harbor views and local seafood, this is not what you are looking for. If you are looking for good, reasonably priced, enormous portions and music memorabilia, you can't go wrong here.
