Muku's has been around for a while and there are good reasons as to why they are still around admist all the new Ramen places opening in Calgary.. However, their quality has deteriorated over the years, that I only go if my friends suggests it - and I used to go there like 2-3 times a month.
Unless you get something crazy or load your ramen with extra toppings, Muku is one of the cheapest place to have a good bowl of ramen. Their soup used to be much more flavorful, but now it's just standard. The portion is a good sized, and getting the combo definitely will fill you up. The noodles are cooked perfectly but they don't add any flavors to the bowl. Their toppings are good, but the menma is usually too hard, and the pork is small and thin.
Their yakisoba (more like a yaki-ramen) is actually quite good too.
