Chicken - normal.
Rice - bland if the sauce they drizzle over the chicken doesn't coat the rice. If the spoonful of rice you take has the sauce, it'll be normal at best.
Maybe I'm spoilt but this chicken rice seems, in my opinion, normal at best. I think it's highly overrated.
Just for completeness, I also ordered a plate from their competitor (ah tai or something like that). That was bland too, more so than tian tian's. What a waste of time.
