I have recently started doing some volunteer work near Old Street tube (Rivington street) one day a week (usually Wednesday) . Rather than travel back home during the rush hour ( I live 50 miles away) I was thinking of staying down for an hour or two and trying some of the many restaurants / bars etc that seem to be in the area. Just looking for some places where I can get an earlyish (6pm) meal, will probably be solo dining some of the time. Any cuisine considered but places where I can just walk in on a whim (no need to make reservations). For example, yesterday I tried a place called Hanoi (Vietnamese) which seemed pretty good and reasonable to me. Are there any real "gems" in the area I should know about?. Anywhere within walking distance is fine (as far as Moorgate for example). Any recommended lunch spots too?
Grateful for your help.
