The diner on Maddox Street is far from short of options, ranging from Hibiscus (over-rated in my opinion) and Goodman (well worth a visit) to the more mundane Patara (Thai) and Browns (part of the chain).
Sumosan (October 2012)
About the worst thing a restaurant could be faulted for is not being made to feel welcome and in every sense this was the impression I took away from Sumosan. The exterior of the restaurant looks forbidding with a passer-by not being in a position at all to discern what may be happening inside, the interior being hidden by full-length blinds.
