It's good for the fast-food kind place it is supposed to be. The first time I went, I bought a Groupon and ordered an iced vietnamese coffee, dan dan noodles and singapore noodles. The vietnamese coffee was kinda gross, but I should have not expected much from the kind of place it is. The dan dan noodles were so far removed from the dish the namesake is from that I had a hard time enjoying it. It tasted fine, but not anything I would ever order again.
The singapore noodles, also very different from the dish it's named after, were surprisingly quite yummy. It had a wonderful peanuty-sauce and plenty of veggies. I have gone back once more with a couple friends and I ordered the same--the singapore noodles.
You just have to order from the menu and try to distance yourself from the dish's name otherwise if you're expecting the actual flavors from the dish's name, you'll be disappointed.
The service is always friendly and welcoming. Unfortunately, I probably won't be back for a while because I no longer work in the area.
