Great hidden spot in Las Vegas! I come from a Korean and Mexican background so this place was perfect for me. The Bulgogi, marinated beef, burrito is a all time great and is an automatic go to dish for around $5 and can usually feed you for two meals. Another recommended item is the Daegi bulgogi, spicy pork, french fries.
For those of you that have hit Robertos Tacos late night and enjoyed their super carne asada fries you will love these. They step it up every week with new specials such as calamari tacos and bulgogi gyros so you never get bored with the menu. The Korean street tacos blend the tastyness of Korean meats with the ease of tacos, I recommend ordering a few at the low price of $1.29. I could go on forever on the best items on the menu so head over and decide for yourself.
If you have friends that aren't too adventurous or little kids Komex can handle that too. They offer sliders, french fries and other basics that are just as good. Because this place is so good and really affordable it can get busy around peak times so don't get frustrated and recognize that if there are tons of people eating there then it must be good.
