Ordered the House Specialty C1 yesterday. I liked the broth. The pork bones though were too much work to eat because they weren't boiled for long enough, however the flavour in the meat was still apparent and also tasty. The noodles were good, nice and soft. Vegetables and other meat toppings were on the scarce side. We weren't aware rice noodles are refillable for free, service didn't really care to inform us. They weren't rude or mean though, just nonchalant.
I don't think I'll really crave this place against other options after trying it out but it's not bad. Kinda sits at okay for me. You could still check it out, if you're looking for something new.
