You're in luck if you want some authentic northern, western Chinese food!!!
1) food: I highly recommend the cold noodles (y'all know what I'm talking about! See photo). There's not many places that can make them as authentically as this place. The spice and the salt is just right. The lamb skewers were also pretty great (told by my parents). My family also loved the beef brisket soup. And I personally loved the eggplant dish (best I've had) and the long beans!!
But again: get the cold noodles.
2) the atmosphere. Right when you walk in you're welcome by the smell of SPICE! And immediately your salivary glands are getting into action and your body's telling you, you're ready to eat! There's also plenty of space, not super crowded, large tables so it'll be good for large parties too.
3) location: very conveniently located at a major intersection in Scarborough. If you're in the area, definitely worth the drop by.
BONUS TIPS: they have a membership I believe it's $20 for 2 years and essentially you get 50-60% off on each dish!! It's super worth it, we got it on our first visit and we amount we spent on the membership was already saved in the first meal. So make sure you ask for it at the beginning! (Membership is cash only though)
