I frequently come here for breakfast on the weekend and lunch or afternoon snack on a weekday and it's always been packed. It's a lot cheaper than other HK-style cafe, however on my most recent trip they seem to have raised their prices :| If they continue to increase their price I don't think I'll be visiting as frequently anymore.
Service is so-so. Don't expect excellent service, but for the price and food it's good for a quick meal. I sometimes order dinner take-out but rarely do 'cause the service is really slow. I once order 4 dishes and they told me the wait would be about 45 mins. I told them I would come back in 45 mins and when I did, they only had 2 of the dishes were ready and that they ran out of ingredients for the other 2 dishes, so I had to order something else and wait again.
My typical go-to orders are satay beef with vermicelli in soup, macaroni in soup with porkchop (so yummy) and 2 eggs, or the 8 piece chicken wings (also really yummy) with cold lemon tea (kinda dislike how they ask for extra $0.75 for ice...). If you order over $10 in the afternoon, they give you a free pineapple bun with butter and if you order lunch, they give you soup.
