It's your typical Hong Kong style cafe/diner...cheap & quick food, very basic eating area, order your food from counter, minimal service with little etiquette, average rating food, and small portions. Don't expect more as this type of setting is expected for your general Chinese cafe/diner.
The only saving grace is the Hong Kong tea is better than average. It definitely has a stronger flavor of black tea with high proportion of evaporated milk making it heavier and creamier. I wouldn't say it's an award winning tea but definitely better than the average tea.
Would I come here again? Probably, if I'm in the neighbourhood for some cheap Chinese food, by myself, and in a rush...sure, why not.
