I've been to salad King 4 times! The experience was different each time... In terms of service. The first time I was there (2 years ago), service was great but the last 3 times I was there, service was very SLOW. If you're not in a rush, it's fine but if you're on a schedule, this is something you need to consider.
In terms of food, I love their stir-fry noodles! It's very delicious! But their noodle soups are very bad!! I only bought it once and ended up not finishing it... It was extremely sour. So advice here: get their stir-fry noodles or curry! Stay away from their noodle soups!
Overall, I do recommend the place to just try out because they do have good food! But it's not my go-to food place!
