Came here on a Saturday for lunch. Surprisingly empty (only 3 tables were used around 12-12:30pm!). Ordered the deep fried crispy chicken ramen and Japanese pork belly udon with HK milk tea. I enjoyed the hot ramen broth and the springy ramen noodles. Each portion was okay for one - definitely closer to snack-sized rather than a stuffed-full lunch. It would be great value during the Monday to Friday lunch special for ~$2 less (~$6.50). I would return for this special, sans kids.
Unfortunately they had only one high chair for toddlers, so another family had to ask to see if we were done with ours so they could use it. We also weren't given any small spoons or knives to feed the kids so it was a bit difficult portioning out the food. Would recommend bringing your own portable highchairs and utensils if you are bringing small children.
Note: For $2 more you can upgrade your drink to a bubble tea.
