Well it's pretty legit, judging by the lack of cleanliness, poor service, and picture menus on the walls (with ZERO English). These are all signs of a Chinese restaurant with excellent food, and the Old House delivered on that front. We had their specialty water boiled fish and the lamb haggis soup, both of which were delicious, came in large bowls, and reminded me of true traditional Asian food. The fish came with a copious amount of spices and was very aromatic; the lamb broth had that richness which I really enjoyed.
On the down side, the dishes arrived very slowly. As mentioned there's pretty much no service whatsoever, but you order by marking on a sheet so there's no chance of them bringing out the wrong thing (and you never need to talk to the waitress! Lol). Of course ambience and all that is also non-existent - I was grateful enough for the moderate A/C.
