Tough area. You could light rail it up to Hampden, where there are a number of places. I saw a sign yesterday of somewhere looking for bussers and hosts, i think food market.

The inner harbor might have something. Mt Vernon itself seems less active than it used to.

Depending where you are, try station north and old goucher neighborhoods: Dutch courage, Clavel, etc. might have something for you.

In my experience, it shouldn’t take long to find something if you’re willing to dish wash. Places sometimes won’t post it, but are often willing to hire a dishwasher or even train you for other positions to cover a variety of roles as necessary
