Our trip to Hong Kong is not completed without going to 千両 Sen-ryo. Sen-ryo is a chain sushi restaurant with many locations in Hong Kong. We usually go to the one in TST, inside the The Sun Arcade on Canton Road. We got there around 6pm near dinner time so they had started dispensing tickets for seatings. They didn't have that last time when we visited a couple years ago, but it wasn't a big deal, we just asked the reception for seats and she printed out a waiting number for us. (You can also take a number yourself from the touch-screen.)
Many sushi restaurants in Hong Kong feature the conveyor belt which is very common and somewhat popular. Sen-ryo also offers dishes from off the menu, and if there's a kind of sushi that isn't on the conveyor, you're welcome to order it off the menu for the same price. Each dish is priced differently by the color of the plate, and the server would tally up the plates at the end of the meal to calculate the total cost (and of course, add those items that you had ordered from the menu also). Depends on what kind of sushi it is, a plate (usually comes with 2 pieces) could range from $18 to $45HK. Some of my favorites? Marinated tuna, real crab meat, crunchy shrimp roll, and spicy scallops!
Don't forget to have the mochi ice-cream!
